The Camco RhinoFLEX 20-foot kit is a sensible first sewer-hose setup because it can be used as one 10-foot section or connected for the full 20 feet. Here is what comes in the kit, where it works well, and what it does not solve.
Scout’s quick verdict
A flexible starter kit for common campground hookups
The RhinoFLEX 20-foot kit is best for RV owners who want a complete, modular setup with a visible elbow and an adapter for common dump-station inlets. It is less appealing if you need maximum puncture resistance or unusually long reach.
What is included
- Two collapsible 10-foot RhinoFLEX hose sections.
- Pre-attached bayonet and lug fittings that swivel for easier alignment.
- A clear 90-degree elbow so you can see when flow has stopped.
- A removable 4-in-1 adapter for common 3-inch slip and 3-, 3.5-, or 4-inch threaded sewer inlets.
- Storage caps for the hose ends.
Using two sections instead of one fixed 20-foot hose is the main practical advantage. At a close connection, deploy only 10 feet. When the sewer inlet is farther from the RV, join both sections.
Who should buy it
This kit fits weekend campers, seasonal travelers, and new RV owners who want the essential fittings in one box. It is also useful for rigs with limited exterior storage because each hose collapses for travel. Camco says the hose and fittings are designed to fit many standard 4-inch square RV bumpers, but bumper interiors, end caps, and attached fittings vary—measure yours before relying on bumper storage.

Strengths
The hose stays where you place it
The reinforced, collapsible design bends around obstacles and holds its extended shape better than a loose, springy hose. Extend only the length you need so the run has fewer low spots.
The clear elbow removes guesswork
Seeing the discharge at the sewer inlet helps you determine when a tank has finished draining and when rinse water is running clear. Keep the valve sequence and rinsing procedure recommended by your RV manufacturer.
Replaceable sections simplify storage
Two pieces are easier to arrange in a compartment than a single long assembly. A damaged section can also be isolated instead of taking the entire 20-foot run out of service.
Limitations
RhinoFLEX is positioned as a durable general-purpose hose, but sharp gravel, dragging, crushing, and UV exposure still shorten hose life. The kit also does not include a sloped hose support, disposable gloves, a dedicated rinse hose, or a shutoff cap for every possible campground layout. Treat those as separate setup decisions.
If you camp for long seasons, frequently use rough sites, or want Camco’s more rugged construction, compare the RhinoEXTREME line. If your dump connection is routinely more than 20 feet away, add only a compatible extension and avoid creating a flat run that cannot drain.
A cleaner setup routine
- Wear disposable gloves and confirm that both RV waste valves are closed.
- Secure the bayonet fitting to the RV outlet before opening any valve.
- Seat and secure the 4-in-1 adapter at the sewer inlet.
- Support the hose with a continuous downhill slope where campground rules require it.
- Empty the black tank first, then the gray tank, following your RV’s instructions.
- Rinse approved components, cap both ends, and store sewer gear away from fresh-water equipment.
Bottom line
The Camco RhinoFLEX 20-foot kit is easy to recommend as a researched starter choice because it covers short and medium hookups without forcing you to deploy all 20 feet. Buy it for its modular layout and useful fittings—not because any sewer hose is indestructible.
