Solid, Reliable, and Makes the Gross Job Way Easier
Style: 20' Rhino Sewer Hose
Solid, Reliable, and Makes the Gross Job Way Easier This is hands-down the best sewer hose kit I’ve used. It’s sturdy, easy to connect, and doesn’t feel flimsy like some of the cheaper ones. The clear elbow is a lifesaver because you can actually SEE when everything is done (which every RVer knows matters). The hose holds its shape, stretches exactly as needed, and packs up neatly. If you’re full-time or travel often, this is the one you want.

Worth the money. Get it.
Style: 20' Rhino Sewer Hose
I am a full time RV'er and these are the best hoses I have worked with. At this point I just do not buy anything else unless I have no choice. Yes, everything fails over time but these last the longest. If you want solid equipment you just don't have to worry about, get these hoses.

Secure, clean hose, poor durability.
Style: 20' Rhino Sewer Hose
The connectors, and plugs work great. I operate an Arctic Fox 990 TC. Plugging the ends keeps any residual in the hose and prevents odors and they ends are very easy to operate. I operate an RV in a climate controlled environment, dumping grey water roughly once every day or two for odor control, with occasional trips dumping more like 5-7 day intervals. I only use one of the two hoses and after about 175 cycles the hose split apart near the end. I shortened it at the break and reattached but within another 10 uses the hose split in the middle. Extending and contracting the hose is hard on it and weakens the folds in the plastic the point of failure within certainly less than 200 uses at 50+F temperatures, so don't expect great longevity out of the hose. I image if you dump in cold temperature, subject it to a lot of movement by leaving it hooked up outside the hose could survive even fewer extensions. If you only dump a few times a year it may last you twenty years or more. The good news is that if you pay attention you'll likely notice the hose split before you run the sewage through it, so if you carry a spare you'll at least be able to dump. I ordered another pair so I can always have at least one spare on hand and I figure my failure rate will be about once every 9 months or so. Camco makes other hoses, including an Extreme that likely doesn't pack tightly enough for two 10' sections in my bumper. I don't need crush resistance, I need durability, so the more expensive hose really wouldn't be an improvement for me since I wouldn't be able to carry a backup. I'm guessing all of these hoses will have a similar durability limitation, especially if extended when cold. I'd like to see a slightly softer, more durable material that will still hold it's shape when dumping, but maybe that's not possible with current plastic characteristics. Main take away is make sure you've got a spare sewer hose section on hand if you have a way to store it.
