Camco RhinoFLEX 39671 10-Ft RV Sewer Hose, 3-In Black

The Camco RhinoFLEX 39671 is the 10-foot sewer hose at the heart of Camco's toughest waste line. It's built from 23 mils of heavy-duty polyolefin reinforced with a steel wire core, and that combination is the whole point. The wire lets the hose hold whatever shape you set it to. Route it around a jack, drop it into a dump inlet at the angle you want, and it stays there until you unhook it and compress it back down. No sagging belly full of waste sitting between your rig and the drain.

This is the hose-only version. You get the 10-foot RhinoFLEX hose and nothing else in the box, so it's the piece you want when you're building out a fresh setup with your own RhinoFLEX swivel fittings, or when the hose on an older run has finally given up but the fittings are still good. The swivel bayonet fittings, the clear elbow, and the 4-in-1 dump-station adapter are all sold separately. If you'd rather have a complete ready-to-dump kit, look at the RhinoFLEX kits that ship with the fittings already attached.

Extended, it reaches a full 10 feet, which covers most spots where the dump inlet sits a little farther from your rig than you'd like. When you're done, it collapses down to just 32 inches. That compressed length matters more than people expect. A hose that packs down to 32 inches drops neatly into a standard 4-inch square RV bumper or tucks into a storage bay without fighting you. The 3-inch diameter is the standard RV sewer size, so it mates up with the connections and dump-station inlets you already deal with. And because the wall stays flexible even after it compresses, you're not wrestling a stiff coil back into shape the next time you set up camp.

Why the steel wire matters, in plain terms. A smooth hose that won't hold a slope leaves low spots, and low spots hold water and solids you'd rather not have sitting there between dumps. The reinforced RhinoFLEX wall keeps the tube round and keeps your downhill run actually running downhill. Set the pitch once and it stays put. That's the difference between a quick, clean dump and standing there shaking the hose to coax the last of it along.

The black polyolefin wall takes the abuse that comes with this job. Dragged across concrete dump pads, parked in the sun at a seasonal site, coiled and uncoiled a few hundred times over a season, it holds up. It's a proven design that plenty of full-timers have run for years without babying it, and it's the same material and wall thickness Camco uses across the RhinoFLEX line. That consistency means a section like this drops right in alongside the fittings and hoses you're already running, with no surprises in fit or feel.

A few honest notes on use. Always dump the black tank first, then the gray, so the gray water flushes the inside of the hose on its way out. Rinse the hose after each dump if your site has a utility spigot, then compress it, cap the ends, and store it out of direct sun when you can. And because this one is hose only, check that your existing RhinoFLEX fittings are in good shape before you head out, since a cracked bayonet fitting will leak no matter how good the hose is. It's also worth carrying a spare pair of disposable gloves and a short bungee to hold the hose supports in place, because a tidy, well-supported run drains faster and cleaner than one that's kinked or drooping. Treat it right and this is the last 10-foot section you'll think about for a long time.
