Camco RhinoFLEX 20-Ft Complete RV Sewer Hose Kit, Clear Elbow with Sewer Adapter, (2) 10ft Hoses, 360 Swivel Fittings (39742) Review (2026)
Updated September 20, 2026 · Research-based review
Our verdict
Camco's RhinoFLEX 39742 kit pairs two 10-ft, steel-wire-reinforced hoses with a clear 4-in-1 elbow adapter and 360-degree bayonet fittings. It suits RVers who want the flexibility of using one or both hose sections depending on how far the dump station sits, though the reinforced hose can puncture if dragged over sharp gravel.

What we liked
- + Two hoses reach far sewer inlets or stay short when you need less
- + Clear elbow shows when the tank runs clear during rinsing
- + 360 swivel fittings make attaching to the RV outlet easier
Trade-offs
- - Hose storage takes up space unless your bumper tube fits it
- - Thinner hose walls can puncture if dragged over sharp gravel
Two-hose flexibility
The kit includes two separate 10-foot hose sections with pre-attached fittings rather than one continuous 20-foot hose, which means a short trip to a nearby dump station can use just one section while a site with a distant sewer connection can join both for the full 20 feet of reach. Each section is built from 23 mil polyolefin reinforced with steel wire, a construction Camco uses across its RhinoFLEX line to let the hose bend and hold a shape rather than sagging or kinking under the weight of flowing waste, which helps keep water moving toward the dump station instead of pooling in a low spot along the hose.
Fittings and the clear elbow
Both hose sections use four-pronged bayonet fittings that swivel a full 360 degrees, which makes lining up the connection at the RV outlet and at the dump station easier than fittings that only thread straight on. The kit's clear elbow sits at the dump station end and includes a 4-in-1 adapter sized to fit 3 inch slip connections along with 3, 3.5 and 4 inch threaded pipes, covering most campground and dump station fittings without a separate adapter purchase. Because the elbow is transparent, it lets a camper see when the tank has finished draining and the rinse water is running clear rather than guessing based on sound or timing alone.
Storage and compressed length
Each 10-foot hose section compresses down to about 39 inches with its fittings attached, and Camco designs the kit so the 4-in-1 adapter can be removed to let the compressed hose fit inside a standard 4-inch square bumper tube, a common storage spot built into many travel trailers and fifth wheels. RVs without a bumper tube built for hose storage will need a separate storage container or tube mounted elsewhere, since leaving the hose loose in a basement bay risks tangling with other gear or picking up debris that could work into a fitting before the next use at a different campground.
Hose durability on rough ground
The steel-wire-reinforced polyolefin construction keeps the hose's shape and resists collapsing under normal handling, but the wall material is still made to flex, which means dragging it repeatedly across sharp gravel, exposed rebar, or other abrasive surfaces at a dump station can eventually wear through a section faster than a heavier duty hose designed specifically to resist punctures. Camco backs the kit with a 90-day limited warranty, which covers manufacturing defects but not damage from rough handling in the field, so RVers who frequently camp on gravel dump pads may want to lay down a mat or guide the hose over hazards rather than letting it drag directly across abrasive ground.
Where this kit fits in Camco's lineup
Camco also sells a heavier duty RhinoEXTREME line built with TPE technology specifically marketed for greater crush and abrasion resistance, at a higher price point than this standard RhinoFLEX kit. For RVers who mostly connect to paved or gravel-free dump stations and want the flexibility of two separable hose lengths at a moderate price, the RhinoFLEX 39742 covers the core task well, while full-timers who regularly deal with rough ground or want a single continuous hose length may be better served by stepping up to the RhinoEXTREME kits reviewed alongside it in this guide.
Frequently asked questions
How long is the hose and can it be shortened?
It includes two separate 10-foot sections that can be used together for 20 feet or separately when a shorter hose is enough.
What sewer connections does the adapter fit?
The included 4-in-1 adapter fits 3 inch slip connections plus 3, 3.5 and 4 inch threaded pipes.
How does the compressed hose store in the RV?
Each section compresses to about 39 inches, and removing the 4-in-1 adapter lets it fit inside a standard 4-inch square bumper tube.
Is this hose puncture resistant on gravel?
It is steel-wire reinforced to hold its shape, but the wall is not built as crush and abrasion resistant as Camco's heavier duty RhinoEXTREME line, so avoid dragging it over sharp gravel.
