Updated for 2026. Dumping black and gray tanks is the chore nobody loves. The right sewer hose kit (and, when the pedestal is too far, a portable tote) keeps that job shorter, cleaner, and less likely to end with a leak in the grass. This guide covers the Camco RhinoFLEX-style kits most owners should start with, the clear elbow and hose support that make dump nights easier, a dedicated rinse hose, and portable tote tanks for dry camping or long walks to the dump station.
How we ranked these
- Hose toughness: steel-wire RhinoFLEX-style construction beats thin vinyl that kinks and splits.
- Kit completeness: clear elbow, 4-in-1 adapter, and caps so you are not shopping three more parts on day one.
- Length and storage: 20 ft total (two 10 ft sections) fits most sites; bumper storage matters on travel trailers.
- Dump-night ergonomics: clear view of flow, hose support for slope, fittings that swivel instead of fighting you.
- Tote capacity and wheels: enough gallons for your tanks, steerable/no-flat wheels, and a real gate valve.
We are not ranking the cheapest thin vinyl “kit” bags. Those fail early and make a mess when they do.
Quick picks
| Gear | Best for | Why it makes the list |
|---|---|---|
| Camco RhinoFLEX 20′ kit | Most owners’ primary sewer hose | Tough hose, clear elbow, 4-in-1 adapter, bumper-friendly sections |
| Camco RhinoFLEX clear elbow | Anyone who dumps without a clear view | Shows when the tank is actually done |
| Camco Sidewinder 20′ | Long runs or uneven ground | Keeps slope so you are not babysitting the hose |
| Camco Rhino 25′ clean-out hose | Tank rinse / flush water | Dedicated orange hose — keep it off your drinking water gear |
| Camco Rhino 36-gal tote | Dry camp / dump too far for a hose | Steerable wheels, gate valve, serious capacity |
| Camco Rhino 28-gal tote | Lighter tote duty | Same Rhino idea, easier to move when full |
Best RV sewer hose kits and totes (2026)
1. Camco RhinoFLEX 20′ kit — best overall sewer hose kit
Best for: Most travel trailers, fifth wheels, and motorhomes that dump at a pedestal or dump station. Skip if: you only need a short replacement hose and already own a clear elbow and adapters.
This is the kit already on our accessories shortlist for a reason: two 10 ft RhinoFLEX sections, clear elbow with 4-in-1 dump adapter, and caps. The hose is steel-wire reinforced so it holds a shape and slope better than floppy vinyl. Swivel fittings save a lot of wrestling at the bayonet.
Measure your typical site. Twenty feet covers most parks; keep an extra 5–10 ft section if you regularly get deep pull-throughs. With the 4-in-1 adapter removed, sections are meant to store in a standard 4″ square bumper on many trailers.

2. Camco RhinoFLEX clear elbow — best “am I done dumping?” upgrade
Best for: Anyone whose kit elbow is opaque, or who wants a spare clear elbow in the bay. Skip if: your RhinoFLEX kit already includes one and it still seals well.
A clear elbow takes the guesswork out of black-tank dumps. When the flow runs clear, you know the tank rinse did its job. The 4-in-1 adapter covers the common dump-station pipe sizes. If you only buy one add-on beyond a decent hose, make it this.

3. Camco Sidewinder 20′ — best hose support
Best for: Long hose runs, soft ground, or any site where the hose wants to sag and trap solids. Skip if: you always dump with a short, steep drop into a nearby inlet.
Hose supports look optional until you spend a dump night lifting the middle of the hose by hand. Sidewinder-style telescoping supports hold a downhill grade so waste actually moves. Pair it with the RhinoFLEX kit on anything longer than a short stub.

4. Camco Rhino 25′ clean-out hose — dedicated tank rinse hose
Best for: Flushing/rinsing black tanks with a hose you will never confuse with drinking water. Skip if: you already keep a clearly marked, dedicated rinse hose and store it away from fresh water.
Cross-contamination is the real risk here. Use an orange (or otherwise obvious) clean-out hose only for tank rinse and sewer-side work, and store it away from your drinking-water hose and filter. This Camco Rhino clean-out hose is the pattern we point to on the accessories page.

5. Camco Rhino 36-gal tote — best portable waste tote
Best for: Boondocking or sites where the dump is a long walk/tow from your pad. Skip if: you always have a sewer hookup at the site and a hose that reaches.
A tote turns “hose won’t reach” into a wheeled trip to the dump. The Rhino 36-gal size is for bigger tanks or fewer trips; steerable no-flat wheels and a gate valve matter more than fancy branding when the tank is heavy. Plan how you will tow or pull it — full totes are awkward without the tow bar / hitch habit.

6. Camco Rhino 28-gal tote — lighter tote option
Best for: Smaller tanks or owners who want a Rhino tote that is easier to move when full. Skip if: you routinely fill large black tanks and hate multiple tote trips — step up to 36 gal.
Same product family as the 36-gal, less capacity. Match gallons to your black tank (or how much you are willing to haul per trip), not to a marketing number on the box.

Sewer hose kit vs tote — which do you need?
Hose kit: default gear for full-hookup camping and dump stations next to the pad. Buy quality hose once; add clear elbow and support as needed.
Tote: when the inlet is too far, you are dry camping, or park rules push dump trips to a central station. A tote does not replace a good hose — you still need fittings and a clear elbow at the dump.
Length, bumper storage, and adapters
- 20 ft (2×10 ft) is the usual sweet spot for RhinoFLEX kits.
- Bumper storage: remove bulky adapters before sliding sections into a 4″ bumper.
- 4-in-1 adapter: covers common dump pipe sizes; keep the gasket clean and replace it when it hardens.
- Wye fittings: useful if you run separate black and gray lines and want one trip to the inlet — only if your plumbing actually needs it.
Dump-night habits that save messes
- Gloves on. Lay out hose with a downhill slope before you open valves.
- Pull black first, then gray (gray helps rinse the hose).
- Watch the clear elbow; rinse until it runs clear.
- Cap everything before you walk away. Store sewer gear away from drinking-water hoses.

Final thoughts
Most owners should start with the Camco RhinoFLEX 20′ kit, add a Sidewinder if the run is long, keep a dedicated clean-out hose for tank rinse, and only buy a Rhino tote if the dump will not reach your pad. Skip bargain vinyl hoses for primary dump duty.
