The best RV sewer hose kits for full timers are the Camco RhinoFLEX 20-Ft Complete Kit as the everyday default, the Camco RhinoEXTREME when you run on gravel and desert sites, and the Lippert Waste Master if flow control matters more than storage. Everything else in this roundup is a variation on those three ideas.
Full-time RV living turns the sewer hose from a seasonal accessory into a wear part. A weekend camper might dump ten times between trips. A full-timer running a 40-gallon black tank with two occupants can be dumping three or four times a week, which adds up to well over 150 dumps a year, in sun, in freezing weather, and with the hose bouncing inside a metal bumper for thousands of miles.
That cadence changes what matters. A mil of wall thickness that would last a weekend camper one season can fail in the first summer of year-round service. A hose that will not compress into a bumper is not a hose you can carry. I have compared the ten complete 20-foot kits below on the four things full-timers actually feel: wall thickness and material, how small the hose packs, how the connection seals, and what owners report after months of use rather than one clean dump.
One honest note on method. I did not tear down and lab-test ten hoses over a year. What follows is built from manufacturer specifications, the full product record for each kit, and a large body of owner reports from RV forums, cross-checked product by product so the durability claims match what the reviews actually say.

1. Camco RhinoFLEX 20-Ft Complete Kit – Best Overall for Full Timers
- 23 mil steel-reinforced polyolefin resists kinking
- Bends without cracking in cold or sun
- 360-degree swivel fittings
- Compresses to 39 in for bumper storage
- Clear elbow shows when the tank is empty
- 3 inch diameter moves waste slower than 4 inch hoses
- Adapter must be removed to fit the bumper
This is the kit I keep coming back to, and the review record backs up why. It carries 22936 reviews at a 4.7 average, the largest sample in this roundup by a wide margin, and the wall is 23 mil polyolefin reinforced with steel wire. A mil is one thousandth of an inch, so you are looking at a wall about twice the thickness of a credit card.
The 3-inch outside diameter is the one honest drawback. A 4-inch hose moves waste noticeably faster, and on a full-timer doing three or four dumps a week that difference adds up over a season.
What sells me on it is the packaging, not just the hose. You get two 10-foot sections with pre-attached fittings, a clear elbow with a 4-in-1 adapter that fits 3-inch slip and 3, 3.5 and 4-inch threaded dump station pipes, and four sewer caps for storage. Nothing gets assembled in a gravel parking lot at dusk.
Each 10-foot section compresses to 39 inches, which is what makes this the default answer for a full-timer. It fits a standard 4-inch square bumper with both sections stowed, which matters more than any spec on the page when your only storage is a hollow steel tube on the rear frame.
When this is the right pick for a full-timer
Choose RhinoFLEX if you move often, dump at a mix of campground and retail stations, and want one kit that handles both without thinking about it. Forum owners report 8 to 10 years of problem-free use from Rhino hoses, and iRV2 posters regularly name the RhinoFLEX or a Valterra as the sensible value in 3-inch sewer lines.
It is also the hose that new full-timers get pointed toward most often. r/traveltrailers and r/RVLiving advice converges on a dual 10-foot RhinoFLEX kit plus a sewer hose support, with the same refrain: you cannot go wrong with Rhino.
When to skip it
Skip it if your only dump options are downhill, uneven, or far from a bumper-friendly parking spot. Slow 3-inch flow plus a sagging run is where pinholes start, and the minor reports of pinholes on this kit cluster around stretched or unsupported hose, not around the material itself.
Also skip it if you dump to a home septic system. This is a gravity hose; the flow rate is not what you want when you are pushing waste uphill into a residential line.
2. Camco RhinoEXTREME 20 Ft Kit – Best for Desert, Gravel, and Heavy Abuse
Camco RhinoEXTREME 20 Ft RV Sewer Hose Kit, Pre-Assembled, Swivel Fittings
- Exoskeleton resists dents and crush damage
- 4 inch diameter gives faster flow
- Pre-assembled with bayonet and clear elbow
- Survives being stepped on and run over
- No fading after a year outdoors
- Each 10 ft section packs to about 57 in
- Stiff sections are hard to separate
- Takes more bumper space than most rivals
RhinoEXTREME is the RhinoFLEX answer to a different question: what happens when the hose lives in the sun and gets dragged across rock. The wall is 24-mil thermoplastic elastomer wrapped around a reinforced polymer core exoskeleton, and the outside diameter is a full 4 inches.
Owners running this kit year-round report no fading, cracking or stiffening after a year of continuous outdoor exposure. Several describe surviving being stepped on and, in one case, run over by a car. That is the kind of abuse tolerance that matters if your dump station is at the far end of a gravel pull-through.
The trade is physical and specific. Each 10-foot section compresses to only about 57 inches, so two sections need a longer or dual-compartment storage arrangement. They also stay stiff, and separating the two halves is genuinely hard for anyone with limited hand, elbow or shoulder strength working alone in the dark.
A small number of reviews report pinholes, some on hoses that arrived already holed. Camco customer service is praised for replacing those units, which is worth knowing if you are two thousand miles from the nearest retailer.
When RhinoEXTREME earns its place
This is the one I recommend for boondockers in the Southwest, for rigs that park on caliche and coral, and for anyone whose connector is a plain screw-on rather than a positive bayonet lock. The thicker exoskeleton and 4-inch bore handle heat and abrasion better than anything else here.
It also flows faster, which shortens each dump. On a three-dump week that is real time you do not spend crouching in the sun.
Where the storage math fights back
The dealbreaker is bumper space. Two sections at roughly 57 inches apiece is a hard fit for a 4-inch square bumper, so full-timers on small rigs often end up carrying one section and coupling the other at the dump station.
A rvboondocker account documented the failure mode on the opposite end of the price range: a cheap accordion-fold hose that split in the pleat after five days of full Arizona sun. Thick-wall TPE with a reinforced core is the direct structural answer to that.
3. Camco Deluxe 20ft Sewer Hose Kit 39658 – Best Compression for a 4-Inch Bumper
- Tightest compression in the roundup at 23 in
- Transparent elbow and clear extender
- Pre-attached 360-degree swivel fittings
- 4 inch bore gives good flow
- Four end caps block residual odor
- Vinyl is more prone to pinholes than TPE
- Very springy and will not stay put
- Occasional fitting-fit complaints
Model 39658 is the kit to buy when storage, not durability, is your binding constraint. Each 10-foot section compresses to about 23 inches, which is the tightest packing in this roundup, and that means both sections plus the fittings live comfortably in a 4-inch square bumper.
Construction is 18 mil heavy-duty HTS vinyl at a 4-inch outside diameter, made in the USA. You also get a transparent elbow and a clear extender, so you can see the waste level instead of guessing whether the tank is empty.
The honest weakness is durability. Several owners report pinholes and sprung leaks developing early, sometimes after only a few uses, and that pattern shows up across thinner-wall vinyl hoses in general rather than being unique to this kit. Quality control on the fittings draws a few complaints too, including one report of an end that did not mate with the owner’s grey water outlet.
On the plus side, the 4-inch bore flows well, and full-time users who keep it recommend a Y connector when the run is stretched tight.
Who this kit suits
Pick the Deluxe if your rig is small, your bumper is your only hose storage, and you are willing to treat the hose as a consumable that gets inspected at every dump. The visibility and the packing are hard to beat.
It also makes sense as a second kit. A full-timer who already owns a heavy hose can keep this one in the bumper as the always-ready spare.
Why a full-timer might pass
At three to four dumps a week, 18 mil vinyl is the thinnest wall class in this roundup, and the failure mode when it fails is a split mid-dump with 40 gallons heading the wrong way. That risk is why most owners here recommend replacing gaskets seasonally rather than stretching hose life.
If your site is gravel, sun-baked, or remote, the heavier Rhino or Titan builds are the safer spend.
4. Valterra EZ Coupler 20-Foot Kit – Best Value
- Lightest 20 ft kit here at 1.9 pounds
- Collapses to 25 inches for storage
- Bayonet hooks keep the hose flat and sealed
- Clearview adapter fits six sewer types
- 18 mil wall limits puncture resistance
- Highest one-star share among the leaders
- Vinyl and plastic crack more readily in freezing cold
The EZ Coupler, model D04-0115, is the value entry in this roundup and the one I would hand a first-year full-timer on a tight budget. It ships as two collapsible 10-foot hoses with rotating bayonet fittings, and each hose folds from 10 feet down to 25 inches.
Two details stand out. The bayonet hook fittings keep the hose flat during a dump instead of letting it curl, and the 90-degree transparent Clearview adapter fits six different sewer types with a gas-tight seal. At 1.9 pounds, it is the lightest complete 20-foot kit here by a wide margin.
The wall is 18 mil, which puts it in the thinner class, and durability feedback is mixed as a result. A 4.5 average with a 6 percent one-star share is the highest one-star share among the top-rated kits, and those negatives cluster around cracking and slow leaks over extended use rather than fitting failures.
Vinyl and plastic also tolerate freezing temperatures less gracefully than the TPE hoses in this list, which matters if you camp through winter.
Where it makes sense
This kit works when your dump stations are close, paved, and reachable without a long run. The flat-keeping bayonet and light weight matter more on a short connection than a heavier wall does, and the 25-inch collapse is genuinely good bumper storage.
Owners replacing a factory hose that split after a season will be happy here. Just plan to inspect it during warm weather.
Where it falls short
Three or four dumps a week for years is a lot of pressure on an 18 mil wall. If you keep it, add a fresh gasket at the start of every season and check the accordion folds for pinholes before you pull the valve open.
Forum veterans rank the long-haul durability question heavily, and Rhino or Titan builds are the recurring answer for people who keep the same hose for eight or more years.
5. Thetford Titan Premium 20 Ft Kit 17902 – Easiest on Cold Hands
- TPE is uncrushable and springs back
- Extended Grip bayonet eases mounting
- 5-in-1 adapter has a real handle
- Resists puncture abrasion and temperature
- Thetford is an established sanitation maker
- Wall thickness and diameter not published
- Black hose gives no visual confirmation
- No published compression figure
The Titan is built around a different priority: doing the connection comfortably when your hands are cold and you are holding a flashlight in your teeth. The star feature is the Extended Grip universal bayonet mount, which makes the fitting to the RV waste outlet far easier to seat in a tight bay.
The Revolve 5-in-1 sewer adapter has a molded handle of its own, so you can maneuver at the dump station without pinching a slippery tube. Four press-fit end caps come in the box, and both 10-foot TPE hoses connect to the outlet and to each other.
Material behavior is the selling point. The TPE is uncrushable and bounces back into shape even after being run over, and it is rated for puncture, abrasion and extreme temperature resistance. For a full-timer who dumps year-round, that resilience is worth more than a clever feature list.
The criticisms are mostly about missing data rather than performance. Wall thickness and outside diameter are not published, so you cannot line it up against the 23 and 25 mil kits, and there is no published compression length to check against a 4-inch bumper.
Why full-timers like it
Handling is the deciding factor in the cold months, and this kit is built around it. The grippy bayonet and handled adapter are the difference between a two-minute connection and a five-minute wrestling match in the dark at a state park in February.
Thetford is also a long-standing holding tank and RV sanitation manufacturer, which matters more to some owners than the badge on the hose.
Where the information gap bites
For a purchase you expect to keep for years, unspecified wall thickness is a real gap. You are trusting the construction claim without a number to verify it against.
The neutral black color also means no clear section, so you are back to counting on the adapter to tell you when the tank is empty.
6. DUMPMAN 20 Ft Sewer Hose Kit – Budget Pick with Real Wall Thickness
- 24 mil TPE at a budget-tier price
- UV-proof construction for year-round sun
- Accordion hose springs back after being stepped on
- Four-prong bayonet with built-in rubber seal
- Clear elbow with removable 4-in-1 adapter
- 3 inch bore moves waste slower
- One of the highest one-star shares at 6 percent
- No published warranty information
DUMPMAN is the interesting budget option here, because it does not ask you to trade wall thickness for the price point. You get 24 mil TPE, which is thicker than the RhinoFLEX, UV-proof construction, and accordion hoses that spring back after being stepped on.
The fittings are properly specified too. Four-prong bayonet fittings with a built-in rubber seal give a tight connection, and the removable transparent 90-degree elbow carries a 4-in-1 adapter that fits 3-inch slip and 3, 3.5 and 4-inch threaded dump station pipes.
Each 10-foot hose collapses to 45 inches, which is workable bumper storage but noticeably longer than the 23-inch compression on the Camco Deluxe.
The 4.4 average reflects a meaningful minority of pinhole reports within weeks of use, a pattern more common with lighter hoses than with the heavy TPE kits. The brand is also less established and publishes no warranty information, which is a real gap when you are three states from a dealer.
Who should buy it
Buy the DUMPMAN if you want thick-wall TPE without the premium tier and you dump at well-maintained sites. The 24 mil wall and UV rating align better with full-time sun exposure than the vinyl kits at the same budget level.
It is also a reasonable second hose to keep in rotation, so one kit can be drying while the other is in the bumper.
Where caution is warranted
No published warranty means you are relying on the seller, and a full-timer cannot easily replace a kit in a remote location. Check the accordion folds for pinholes during the first few dumps rather than assuming the wall rating covers you.
The 3-inch bore also means longer drain times than the 4-inch kits, which you will feel three or four times a week.
7. Valterra Viper 20-Foot Kit – Thickest Published Wall
- 25 mil wall tied for thickest published
- 135 mil beading resists abrasion
- Beading helps the hose hold shape
- Clearview adapter shows when draining ends
- Four drip caps contain residual moisture
- Poor compression at 50 inches per section
- Bulkier 28 by 9 inch packed size
- Fitting reliability and detaching caps draw complaints
The Viper, model D04-0475, is built for abrasion resistance. Its wall is 25 mil TPE with 135 mil protective beading running along the outside, and owners credit that beading with shape retention and resistance to scuffing on rock and gravel.
The 90-degree transparent Clearview adapter fits six sewer types with a gas-tight seal, and the kit includes four drip caps to hold residual moisture in storage. Bayonet rotating fittings with hooks keep the hose flat during a dump.
Here is the catch, and it is a big one for full-timers. Each 10-foot hose collapses from 10 feet to 50 inches, effectively double the storage length of most competitors, and the packed kit measures 28 by 9 inches. This is one of the hardest kits to fit in a standard bumper.
The 4.3 average is the lowest here, with a 10 percent one-star share. Complaints concentrate on storage bulk and fitting reliability, including leaks at connections and end caps that detach in normal use.
When the Viper makes sense
Choose the Viper if you dump on abrasive surfaces constantly, if you have exterior storage that is not a 4-inch bumper, and if wall thickness matters more to you than packed size. The beading is genuinely the most aggressive scuff protection in this roundup.
Several owners comparing it to the Camco RhinoEXTREME consider them comparable builds, which tells you where it sits in the category.
When it does not
Skip it if the hose lives in a bumper. A 50-inch section in a small rig is the difference between a kit you carry and a kit you leave behind, and full-timers do not have a second storage location.
The lowest rating and highest one-star share in the roundup also make it a harder sell for someone planning to keep a hose for a decade.
8. Lippert Waste Master 359724 – Best Flow Control for Home Dumping
Lippert 359724 Waste Master 20’ Extended RV Sewer Hose Management System , Green
- Integrated shut-off valve controls flow
- Hose stays extended to the length needed
- Helical coil with smooth bore resists trapping
- Cam lock gives a leak-proof connection
- Nozzle clear view port confirms empty
- Heaviest kit listed at 9 pounds
- Integrated nozzle is harder to replace
- Fixed 20 ft length with no second section
The Waste Master is not really a hose in the same category as the others. It is a managed system: a UV-protected hose with a helical coil on the outside, a smooth interior bore that resists trapping waste, and a permanently connected nozzle with an integrated shut-off valve, an easy-grip handle and a clear view port.
That valve is the reason to consider it. Almost every other kit here dumps until the tank is empty with no way to stop mid-flow, which is exactly the feature you want when you are pushing waste into a home septic line or dealing with a backed-up park inlet.
The hose stays extended to the exact length required during use, so it does not sag or need coiling on a downhill run, which is where most other hoses develop low spots and pool waste. The 90-degree discharge port on the nozzle fits and secures into a sewage inlet, and the CAM lock connector gives a leak-proof seal at the RV outlet.
Compressed, it measures 5 feet 6 inches. It is also the heaviest kit here at 9 pounds, with a fixed 20-foot length and no way to add a second section for longer reaches.
Why a full-timer would pay up for it
The shut-off valve plus the clear view port removes the two biggest annoyances of weekly dumping: overshooting the inlet and guessing when to stop. r/RVLiving members running sewer ejector pumps for septic tie-ins at home describe that workflow, and this is the hose side of it.
The no-sag design also means long or downhill runs stop being a problem, which is the fix forum veterans point to for pinhole development on unsupported hose.
Why it is not the default
It is the heaviest and most expensive option in the roundup, and the integrated nozzle and valve add parts that can fail and are harder to replace than a plain hose. The 9 percent one-star share is the second highest here, with reports of valve and connector issues.
Check the warranty channel before you buy. Drain Master excludes purchases made through third-party marketplaces from its longer manufacturer warranty, and a full-timer should know that before checkout rather than after a valve fails in the desert.
9. Valterra Silverback 20-Foot Kit – Best Polypropylene Build
- 100 mil beading resists abrasion and scuffing
- Polypropylene springs back after compression
- Owners report no odor retained after use
- Considered an equal RhinoEXTREME replacement
- Also offered in a 15 ft length
- Some owners call the material thin
- Multiple reports of connection leaks
- Reports of pinholes and detaching end caps
The Silverback, model D04-0675, is the polypropylene option in this roundup, and polypropylene is a material you do not see in most of the category. It springs back after compression and resists cracking in high heat, and the 100 mil protective outer beading guards the ribs from scuffing.
Long-term full-time owners report these hoses holding up in sun and foot traffic, not retaining a sewage smell after draining, and holding together with two tanks. Several buyers came to it as a lower-cost replacement for Camco RhinoEXTREME and consider it comparable.
The negatives are concentrated in connections. Multiple reviews describe leaking at the hose-to-hose and hose-to-RV joints even with gaskets correctly seated, and there are reports of pinholes within roughly half a dozen uses and end caps blowing off in normal use.
Two specs to note. The listed wall is 0.635 millimeters rather than a mil figure, and the kit ships with a single clear 90-degree universal adapter rather than a clear elbow at each end.
Who it fits
Pick the Silverback if you want a hose that tolerates heat and does not hold odor, and if you are comfortable checking the fittings at every dump. It is also the only kit here you can buy in a 15-foot length if your storage is really tight.
Valterra also supplies several RV holding tank manufacturers, which matters to owners who want OEM-style parts.
Who should look elsewhere
If leaks at the joints are your main fear, this is not the kit. That complaint pattern appears often enough that it is not a one-off, and tightening fittings will not fix it.
The 387-review base is also the second thinnest here, so treat the long-term reports as encouraging rather than proven.
10. Amazon Basics 20 ft Kit – Simplest Starter Kit
- Complete package for a first dump
- Includes four-in-one converter and four covers
- 4.6 average with 3 percent one-star
- Use one section alone for short reaches
- Material and wall thickness not published
- Thinnest review base here at 172
- No swivel fittings or clear elbow listed
- Single-piece covers are easy to lose
The Amazon Basics kit does one job simply. Two 10-foot sections total 20 feet, and the box includes four storage covers plus a 90-degree four-in-one ground converter, which is everything you need for a dump out of the box.
Its 4.6 average carries a 3 percent one-star share, the lowest here, but that rating sits on only 172 reviews. It is the thinnest sample in the roundup, so the number tells you less than a 4.6 across 22936 reviews would.
The real limitation is documentation. No wall thickness, no material, and no outside diameter are published anywhere in the listing, so durability claims for this kit are effectively untested in the review record. No swivel fittings or clear-view elbow are listed either.
On a full-timer, buying a hose whose entire durability question is unanswerable is a gamble you do not have to take.
When it works
It is a sensible first hose for a new owner on a strict budget, and the two-section format lets you use a single 10-foot section for short reaches and carry only what you need.
Several owners mention the covers rather than the hose when describing what they like about it, which tells you where the value sits.
When to step up
Once you are dumping three or four times a week, move to a kit that publishes its wall thickness. You cannot budget for replacement or argue about pinholes without knowing what the hose is made of.
Save this one as a backup hose or a loaner for a guest rig.
How Thick Should an RV Sewer Hose Be?
At least 23 mil for anyone dumping weekly, and 25 mil for heavy or abrasive use. A mil is one thousandth of an inch, so a 25 mil wall is thinner than a credit card, and 18 mil vinyl is roughly the class that ends its life after a season of full-time service.
The tiers break down like this. HTS vinyl at 18 mil appears in the Camco Deluxe, Valterra EZ Coupler, and the thinner kits in this roundup, and it is a weekend-camp tier. Polyolefin at 23 mil with steel wire reinforcement, as in the RhinoFLEX, is the sensible floor. TPE at 24 to 25 mil, as in the RhinoEXTREME, DUMPMAN, and Viper, is the heavy tier.
Thicker is not automatically better, though. Stiffer hose is harder to couple and harder to compress, which is why the thickest builds in this roundup also have the worst storage numbers.
For a full-timer, match the wall to your ground. Asphalt campground with a short run, 18 mil is workable. Gravel, caliche, and desert pads, stay at 23 mil or above. Rock and long hauls, 25 mil TPE with beading.
15 Ft or 20 Ft? What Length a Full-Timer Actually Needs
Buy 20 feet, delivered as two 10-foot sections, because a full-timer will eventually meet a dump station at the far end of a lot they cannot pull into. The two-section format also lets you use a single 10-foot section for short reaches and carry only what you need.
The counterargument is storage. Twenty feet of hose is genuinely hard to pack into a small rig, and some full-timers end up carrying more length than they need just to avoid buying a coupler.
Everything in this roundup is a 20-foot kit for that reason. The 15-foot option exists, and the Valterra Silverback is available in that length, but it is the choice for owners with confirmed short runs.
The longest hoses sold for this application are managed systems like the Lippert Waste Master, which extends 20 feet and retracts to 5 feet 6 inches, so length and storage are not always a straight tradeoff.
If you are planning to sell the rig, do not modify the dump outlet for a cam-lock system. A permanently altered outlet narrows the resale pool, and most of the mechanical advantage can be had with a bayonet kit.
Camco RhinoFLEX vs RhinoEXTREME: Which Camco Do Full-Timers Need?
RhinoFLEX is the pick for most full-timers because 23 mil polyolefin packs to 39 inches per section, flows predictably, and is the most-reviewed kit in the category. RhinoEXTREME is the pick when the ground wins: 24 mil TPE with a reinforced polymer core, 4-inch bore, and about 57 inches of compressed length per section.
Both are Camco, both are made in the USA, and both carry a one-year limited warranty. They differ in material family, diameter, storage footprint, and how stiff they are in your hands.
That last point matters more than most spec sheets suggest. RhinoEXTREME sections are hard to separate, which is a real problem for an older full-timer or anyone working alone in bad light.
SKU confusion between the two models is a documented source of returns, so check the model number on the box rather than the color.
Bayonet vs Cam-Lock: Which Connection Lasts?
Bayonet fittings last longer for full-timers because they are the standard, they require no modification to the RV, and they come apart for cleaning. Cam-lock gives a tighter seal, but it is typically glued to the outlet permanently.
Almost every RV dump outlet uses a 3-inch, 4-prong bayonet, and virtually every kit here connects to it. The 4-in-1 dump station adapter on the far end is what handles variety, fitting 3-inch slip plus 3, 3.5 and 4-inch threaded station pipes.
A 4-prong bayonet with a built-in rubber seal, as on the DUMPMAN kit, gives you a tight connection without relying on friction. Fittings that swivel 360 degrees, found on the RhinoFLEX, Camco Deluxe, and several others, are what let you connect from an awkward angle.
The Lippert Waste Master is the cam-lock exception in this roundup, pairing a CAM lock connector and ball valve kit with the permanently connected nozzle. It seals better and controls flow, at the cost of a permanently modified outlet.
Before you buy anything, look at your dump valve. Worn bayonet prongs or a bent pin cause drips that get misdiagnosed as a bad hose, and tightening will not fix either one.
What Actually Kills a Sewer Hose
Four things end RV sewer hose life, and each has a specific fix. Knowing which one is eating your hose saves you from replacing a perfectly good hose with the same mistake twice.
Ultraviolet exposure. Year-round sun degrades the outer layer until the hose cracks and then splits, often in an accordion pleat where the material is already stretched. Fix: run the hose in shade under the rig, and cap both ends when it is not in use.
Bumper abrasion. A hollow metal bumper bounces the hose against bare steel for thousands of miles, and one owner group described it as a rock tumbler. Fix: put the hose in a protective sleeve or bag and keep the caps on, because a capped hose does not slide as freely.
Pinholes from unsupported or overstretched runs. Sag on a long or downhill connection creates low spots where waste pools, and the pressure of a full tank forcing through a kink opens a pinhole. Fix: use a sewer hose support, and never stretch the hose beyond its length.
Gasket hardening. The rubber at the elbow and the bayonet hardens, cracks, and produces a persistent drip that tightening will not fix. Fix: replace the gasket at the start of every season. It is a small part and the single cheapest life extension available.
Storing the hose damp belongs on that list too, because the swamp smell that follows is what usually ends a hose’s usable life. Rinsing and bleach will not fully fix it.
Storage: Fitting 20 Feet Into a 4-Inch Bumper
Check the compressed length of each section before you buy, because a 4-inch square bumper only accepts sections in the 23 to 45 inch range. Anything at 50 inches or more will not go in.
The measured numbers in this roundup are 23 inches per section for the Camco Deluxe, 25 for the Valterra EZ Coupler, 39 for the Camco RhinoFLEX, 45 for the DUMPMAN, 50 for the Valterra Viper, and about 57 for the Camco RhinoEXTREME. The Lippert Waste Master retracts to 5 feet 6 inches as a single managed coil.
Two details catch people out. The removable 4-in-1 adapter on several kits has to come off before the hose fits the bumper, and you need to plan for the elbow and caps as well as the hose itself.
Whatever you do, dry the hose completely before you stow it. A hose stored damp all summer in a warm bumper develops an odor that no amount of rinsing removes.
If your rig has no usable bumper cavity at all, a dedicated exterior compartment is worth building. One r/traveltrailers owner built exactly that to avoid stuffing hose into interior cubby space, and it is a better long-term answer than overpacking a bumper.
The 5-Step Cleaning and Drying Routine
At three or four dumps a week, cleaning is a routine and not an afterthought. The whole process takes a few minutes and it is the difference between a hose that lasts years and one that gets replaced because of smell.
Flush in reverse. After the tank reads empty, run water back through the hose with the elbow pointed back toward the RV so the high flow scours the interior bore.
Rinse the fittings. Take the elbow and bayonet apart, rinse each piece separately, and check the gasket while it is in your hand.
Work a soft brush or the rinse cap through the length. A dedicated rinse cap attached to a garden hose is the tool for this, and it is far cheaper than replacing a hose.
Cap both ends immediately. Press the storage caps on while the hose is still wet, and keep them on in storage so the ends do not collect dirt.
Dry fully before stowing. Hang or lay the hose out of the closed bumper until it is dry to the touch, then coil it loosely. Do not coil it tightly while it is still damp.
Do this every dump and the odor problem largely disappears. Skip it and you will be shopping for a new hose sooner than the wall thickness suggests.
Do Full-Timers Need a Macerator Instead of a Hose?
Most full-timers do not need one, but a specific group absolutely does. A macerator is a pump that grinds and pushes waste uphill, and it is the answer when gravity flow fails you.
You want a macerator if you are dumping to a home septic system where waste must move against a grade, if your dump station sits below your sewer outlet, or if the reach is long enough that a gravity hose sags and pools. It also helps if you are dealing with a backed-up park inlet that cannot take a fast, high-volume dump.
You do not need one if your sites are flat, paved, and close. A gravity kit at 4 inches of bore will empty a 40-gallon tank faster than you can pump one, and the pump system adds maintenance and winterization to the list.
A portable tote is a third option, and it solves a different problem from both. A tote moves waste when the hose will not reach a connection at all, which is a distance problem rather than a pressure problem.

Accessories a Full-Timer Actually Uses
Four accessories earn their place on a full-timer rig, and one of them prevents a real failure mode.
A sewer hose support. This is the one people argue about on forums and the one that actually matters. Forum veterans are clear that supports are not optional at downhill or uneven dump stations, because the support is what stops pinhole development. It is the highest-value accessory on this list.
A wye splitter adapter. Lets you drain black and grey together, which roughly halves the number of connections you make each week. For a full-timer that is a real reduction in wear on the bayonet and in time spent crouching.
A rinse cap and a backflush attachment. A rinse cap on a garden hose turns cleaning into a two-minute job, and a backflush head lets you push water backward through the hose with more force than the RV plumbing can.
Spare gaskets and end caps. A full set of gaskets is a trivial cost and a seasonal swap that prevents most persistent drips. Losing a single press-fit end cap is the most common packaging complaint across these kits, and a spare costs almost nothing.
One category-adjacent pick worth knowing about: if you are already replacing a lot of exterior hardware, our guide to retractable hose reels covers the freshwater side of the same storage problem.
Frequently Asked Questions
What is the best RV sewer hose for long-term use?
The best RV sewer hose for long-term use is a 20-foot kit built from 23 mil polyolefin or 24 to 25 mil TPE. Our top pick is the Camco RhinoFLEX 20-Ft Complete Kit, which pairs a 23 mil steel-reinforced wall with sections that compress to 39 inches for bumper storage. Forum owners commonly report 8 to 10 years of service from Rhino hoses.
What is the recommended length for an RV sewer hose kit?
Twenty feet, supplied as two 10-foot sections, is the recommended length. It covers the dump station at the far end of a lot you cannot pull into, and the two-section format lets you carry only one 10-foot section for short reaches. Fifteen feet makes sense only if you have confirmed short, close runs.
What is the difference between the Camco RhinoFLEX and RhinoEXTREME?
RhinoFLEX uses 23 mil steel-reinforced polyolefin at a 3-inch diameter, and each 10-foot section compresses to 39 inches. RhinoEXTREME uses 24 mil TPE with a reinforced polymer core exoskeleton at a 4-inch diameter, compressing to about 57 inches per section. RhinoFLEX packs and couples easier; RhinoEXTREME resists abrasion and flows faster.
How thick should an RV sewer hose be?
At least 23 mil for weekly dumping, and 25 mil for heavy or abrasive use. A mil is one thousandth of an inch, so a 25 mil wall is thinner than a credit card. 18 mil HTS vinyl is a weekend-camp tier that tends to develop pinholes under a full-timer’s three or four dumps per week.
What is the most durable RV sewer hose?
The most durable builds in this category are 24 to 25 mil TPE hoses with reinforced polymer cores and protective beading, such as the Camco RhinoEXTREME and the Valterra Viper. The Valterra Viper carries 135 mil protective beading for abrasion resistance, while the RhinoEXTREME survives being stepped on and run over. Forum owners most often report 8 to 10 years from Rhino hoses.
How do I store a 20 foot RV sewer hose?
Dry the hose completely, then coil it loosely and cap both ends. For bumper storage, compare compressed section lengths against your cavity: 23 to 45 inches per section fits a 4-inch square bumper, while 50 inches or more generally will not. Store the hose in the shade where possible, and never store it damp, because trapped moisture causes an odor that no rinse removes.
How often should I replace my RV sewer hose?
Replace it when you see pinholes, splits in the accordion folds, a hardened or cracked gasket, or a fitting that leaks with the gasket correctly seated. A full-timer dumping 150 or more times a year should inspect the hose at every dump and replace the gaskets at the start of each season. Owners running Rhino hoses commonly report 8 to 10 years of service.
Can you leave my RV sewer hose connected all the time?
You can leave it connected, but keeping the valve closed and both ends capped prevents drips and blocks sun damage. Do not leave the sewer valve open with the hose connected, because an open valve with a rising tank allows waste to run back into the hose and sit there. This is a common cause of odor and pinhole failure.
Which RV Sewer Hose Kit Should You Buy?
For most full-timers, the Camco RhinoFLEX 20-Ft Complete Kit is the right buy. It holds 23 mil steel-reinforced polyolefin, packs to 39 inches per section, carries a clear elbow and 4-in-1 adapter, and has the deepest owner record in the category at 22936 reviews.
If you camp on gravel and caliche, move up to the Camco RhinoEXTREME for 24 mil TPE at a 4-inch bore, and accept the larger compressed length. If your bumper is the only storage you have, the Camco Deluxe 39658 compresses to 23 inches per section and nothing else here comes close.
If you need to stop the flow mid-dump, the Lippert Waste Master is the only kit with an integrated shut-off valve, and it is also the only one built around a helical coil that will not sag on a downhill run. Check its warranty channel before buying through a marketplace.
The rest sort themselves by situation: Thetford Titan for cold hands, Valterra EZ Coupler for weight and value, DUMPMAN for thick wall at a budget tier, Valterra Viper for abrasion with exterior storage, Valterra Silverback for a 15-foot option, and Amazon Basics as a first hose or a loaner.
Whichever you choose, buy a spare gasket set the same day, and run the 5-step cleaning and drying routine at every dump. That habit costs nothing and does more for hose life than any brand on this list.
