Camco RhinoEXTREME 15-Foot Camper/RV Sewer Hose Kit, TPE Technology, Pre-Attached Rhino Swivel Fittings (39861) Review (2026)

What this hose is built for

The RhinoEXTREME 39861 is a 15-foot RV sewer hose kit built from 23 mil thermoplastic elastomer (TPE) rather than basic vinyl. Camco states the material will not dent or rust, and it resists crushing if someone accidentally steps on it while it is stretched between the RV and the dump inlet. That toughness matters more than length for most weekend campers, since a hose that survives being dragged over gravel and rocks for a season is worth more than one that looks fine in the box but splits within a year. The 15-foot length suits sites where the sewer connection sits close to the RV pad. For pull-through sites or spots with a distant inlet, the reach can fall short, so it helps to know your typical site layout before buying the shorter kit over a 20-foot version.

Fittings and everyday use

The kit ships with Camco's Rhino swivel fittings pre-attached at both ends, along with snap-on storage caps. Because the fittings are already crimped to the hose, there is no assembly step before the first trip, and the swivel action lets you rotate the hose without twisting it while connecting to the RV outlet or the dump station inlet. The tradeoff is that the fittings are fixed rather than field-replaceable, so if a coupling cracks or a gasket fails, the practical fix is usually a new hose rather than a spare part. For most owners this is an acceptable tradeoff since the fittings are the least common failure point compared to punctures along the hose body.

Cold weather and abrasion resistance

Camco markets the RhinoEXTREME line around abrasion resistance, aimed at reducing pinholes and leaks that plague thinner hoses when dragged over rough pavement or gravel dump pads. The company also states the hose has been tested down to negative 40 degrees Fahrenheit, which is relevant for late-season or shoulder-season campers who dump in cold mornings when standard vinyl hoses can stiffen and crack. This is a meaningful upgrade over entry-level clear or thin-wall hoses that tend to become brittle once temperatures drop, even if most RVers will never test the hose anywhere near that extreme.

Storage and the 4-in-1 adapter

A removable 4-in-1 adapter is included, which lets the hose store inside a standard 4-inch square RV bumper if your rig has that storage option. Storage caps snap onto both ends when the hose is not in use, keeping residue contained and the fittings protected from road grit while traveling. Because the hose compresses down for a 15-foot kit, it takes up noticeably less space in a storage bay or bumper than a 20-foot equivalent, which is worth factoring in for smaller trailers and truck campers where bay space is tight.

Warranty and who should buy it

Camco backs the RhinoEXTREME kit with a one-year warranty against defects in material and workmanship from the date of purchase, in line with the rest of the RhinoFLEX and RhinoEXTREME lineup. This kit makes sense for RVers who want a step up from basic hoses without moving to a full 20-foot setup, and who typically camp at sites with a reasonably close sewer connection. Anyone who regularly encounters back-in sites with distant hookups should size up to a 20-foot RhinoEXTREME kit instead, since a hose that is stretched taut is more prone to pulling loose or kinking at the fittings.
