Camco RhinoFLEX Review

The sewer hose that came with our used 2019 Class C motorhome was not a bad hose on the day we bought it. It was just old, thin, and stiff, the kind of hose that had been sitting in a bumper compartment long enough to forget what a campground looked like. On our second trip, at a dump station in Arkansas, it split near the fitting. No spray, no drama, just a drip that ran down my glove while Dean held the other end. We rinsed the concrete and threw the hose away. That was three years ago, and it is why the Camco RhinoFLEX 15 ft kit went into the outside storage bay before our next trip.

I am Marla Pruitt, 64, and Dean and I bought the motorhome about three years ago. It is a 25-foot Class C, and we tow nothing. We take about six trips a year, mostly 4 to 10 nights at state parks and private RV parks in Texas, Oklahoma, Arkansas, and New Mexico. Biscuit, our 7-year-old beagle mix, rides with us. We are not gear testers. We are a retired couple who wants the sewer part of the trip to be short, clean, and unremarkable. The Camco kit has done that for us, with a few limits I will get to.

How I've Used It

We bought the Camco RhinoFLEX after that second trip, and it has been the only sewer hose we have used since. It lives in a lidded plastic bin in the outside storage bay, away from the drinking-water hose. I keep the bin on a shelf so I am not kneeling in gravel to dig it out. The kit is one 15 ft hose with the fittings already attached, a clear elbow, and a 4-in-1 adapter. The first time I opened it, I liked that I did not have to assemble a puzzle at the dump station. The swivel bayonet fittings twist onto the RV outlet, and the adapter goes into the campground pipe. The clear elbow lets me see the flow start and stop, which is worth more to me than it sounds.

At a full hookup site, I leave the hose connected for the length of the stay. At a dump station, I connect, dump, rinse, and put it back in the bin. The 4-in-1 adapter has fit every dump station pipe we have met in Texas, Oklahoma, Arkansas, and New Mexico so far, including the 3-inch slip fittings the listing says it handles. I cannot tell you it will fit every pipe in the country. I can tell you that I have not had to borrow an adapter from a neighbor. The hose is 3 inches in outside diameter and 15 ft long, and it weighs about 3 pounds, so it is not a burden to carry from the bin to the outlet.

I do not baby the hose, but I do not abuse it either. I keep it out of the sun when we are not using it, and I do not drive over it or drag it across sharp gravel. After a dump, I rinse the inside as well as I can, lift the hose to drain it, and coil it loosely before it goes back in the bin. The clear elbow gets a separate rinse because the inside is the part that tells the truth. If it looks cloudy, I rinse it again. That routine takes a few minutes, and it is the difference between a hose that stores clean and one that makes me dread opening the bin.

The Parts That Matter at a Dump Station

The feature I notice most is the pre-attached fittings. On our old hose, the fitting was a place where the hose could fail, and it did. The Camco fittings are attached at the factory, and the bayonet ends feel solid in the hand. I still check them before every trip. I look for cracks at the collar and make sure the locking rings are seated. That is a two-minute habit, not a complaint. The swivel bayonet fittings also make the connection easier when the outlet is at an awkward angle. I can turn the fitting without twisting the whole hose.

Second is the clear elbow. I did not think I cared about seeing the flow until I had it. When I open the valve, I can watch the tank empty and know when it is done. When I rinse, I can see the water run clear. That saves me from guessing and from opening the valve again to check. The clear elbow is not a fancy feature. It is a simple window into a job I would rather not think about. On a windy day, when I am trying to finish before the line at the dump station gets long, that window is the difference between a confident stop and a lot of second-guessing.

The 4-in-1 adapter is the third part I care about. It is one piece that covers several pipe sizes, so I am not carrying a bag of separate adapters. The listing says it accommodates 3-inch slip fittings, and that has been the size we see most often at the parks we use. I still carry a pair of gloves and a small bottle of hand sanitizer in the bin. The adapter does its job, but it does not make the job clean. Nothing does. I like that the kit gives me the parts I need in one place, without a lot of extra pieces I would lose.

Where the 15 Ft Length Shows Its Limits

The 15 ft length is the right size for most full hookup sites we use. It reaches from the RV outlet to the campground pipe with a little slack. On a few sites, the pipe is at the back of the pad, and I have had to move the motorhome forward a foot or back up a foot to make it comfortable. We do not carry an extension. That is a choice, not a flaw in the hose, but it is the main limit of this kit. If you have a long run to the outlet, this kit alone may not be enough. The hose is 15 ft, not 20, and that is the tradeoff for a kit that coils into a small bin.

Another limit is that the hose is a hose. It is not a permanent pipe. I would not drive over it or leave it stretched tight across a walkway. I route it along the edge of the pad and keep it out of the path. At one site in New Mexico, the outlet was under a small shrub, and I had to kneel to make the connection. The hose reached, but I was glad I had gloves. That is not the kit's fault. It is just the shape of some campsites. I plan for it now. I look at the site map before I book, and I ask at the office if I am not sure.

The Camco RhinoFLEX also comes with a limited one-year warranty. I would like a longer one, but I have not needed it. The hose has not split, the fittings have not cracked, and the elbow has not come loose. If you expect a hose to last a decade with no care, you will be disappointed. If you rinse it, store it out of the sun, and do not drag it over rough ground, it should give you several seasons. Ours has. I am not gentle with it, but I am deliberate. There is a difference.

How It Has Held Up Over Three Years

Three years and roughly eighteen trips is not a laboratory test. It is enough to know whether a hose survives real use. Ours has been in Texas heat, New Mexico wind, Arkansas rain, and a few cold mornings in Oklahoma. It has been connected and disconnected maybe a hundred times. The hose has not split, the fittings have not cracked, and the elbow has not come loose. I rinse it at the dump station and let it drain before it goes back in the bin. That is the whole maintenance routine. No tools, no repair kit, no drama. The only thing that has changed is the label on the bin, which I wrote in marker so I would not grab the wrong one.

The one thing I watch is the collar where the hose meets the fitting. That is where the old hose failed, so I am attentive to it. So far, the Camco collar looks the same as it did on day one. I also check the adapter for grit. A little sand in the locking tabs can make it feel stiff. A rinse fixes it. These are small habits, not repairs. I would rather spend two minutes checking than five minutes dealing with a stubborn fitting at a dump station with a line behind me. That is the kind of practical math I do now.

The listing describes the material as polyolefin and alloy steel, and the wall as 0.023 inches thick. I am not an engineer, so I cannot tell you what those numbers mean for burst pressure or long-term flex. I can tell you the hose has not kinked at the fitting or split at the collar in three years. It has stayed flexible enough to coil in cool weather. It has not turned brittle in the Texas sun. That is the report I can give you from the passenger seat, not from a test bench.

What a New RVer Should Know

Buy the kit before you need it. That sounds obvious, but our old hose taught us that the sewer hose is not the place to save space or time. When you are at a dump station with a line behind you, you want fittings you trust and a hose that does not fight you. The Camco kit is not the only choice, but it is the one I would buy again for a 25-foot Class C. I would also buy a lidded bin for it if the kit did not come with one. Ours did not, and the bin has been worth the shelf space.

Keep the sewer hose away from your drinking-water hose. Ours lives in a separate lidded bin. That is not a product feature. It is just good practice. Wash your hands after you handle it, and wear gloves if you are going to handle the bayonet fitting. The clear elbow makes the job easier to judge, but it does not make the job clean. Nothing does. I also keep a small bottle of hand sanitizer in the bin and a pair of nitrile gloves in the pocket of my camp chair. That way I am not searching for them when I need them.

Check the length before you commit. Measure from your RV outlet to the campground pipe at the sites you use most, or at least think about the last three sites you booked. If the run is usually short, 15 ft is plenty. If it is often long, plan for an extension or a different kit. The Camco RhinoFLEX has been a good hose for us because our trips are mostly full hookup sites and dump stations with short runs. It has made the sewer part of the trip ordinary, which is exactly what I wanted. I do not think about it until I need it, and then it works.

Three years, about eighteen trips, and the collar that failed on our old hose has not failed on this one.

Who This Is For

This kit makes sense for a couple in a Class C or travel trailer who uses full hookup sites and dump stations, wants the fittings already on the hose, and does not want to carry a bag of adapters. It suits a 25-foot motorhome like ours because the outlet is close to the rear and the 15 ft hose reaches most pedestals with slack. It also suits anyone who has had a hose fail at the collar and wants a sturdier replacement. If you are retired, travel a few times a year, and want the sewer job to be ordinary, this is the kit I would put in the bin.

Who Should Skip It

If you routinely stay at sites where the sewer inlet is 20 ft or more from your outlet, this 15 ft kit alone will not do it. You would need an extension, and we do not carry one. If you want a hose you can leave connected all season in one spot and never move, a permanent setup might suit you better. If a one-year limited warranty is too short for your comfort, look at that before you buy. And if you are not willing to rinse and store the hose after each dump, no hose will stay pleasant. This one is no exception.
