  • Durable and Good Quality, the RhinoEXTREME are the Strongest Hoses Out There
As a full time RVer this is the standard set to buy. Seriously strong hoses. I have two dump valves on my RV and routinely set up two hoses through the Y. I had previously bought a Viper set of hoses but they were not as durable as the RhinoEXTREME and I bought a second set of the RhinoEXTREME to replace the Viper. Worth the price. Highly recommend for serious RVers. Also recommend the Camco hose stands that expand. ... show more

  • RV Sewer Hose
Living full time in my RV. This is a great idea to get it all that is needed to get started for setting up sewer! Quality is great, sturdy yet flexible! Great value for the money

  • The unsung hero of crappy situations!
Let’s face it—no one dreams of bonding with their RV’s sewage system. But this hose? This glorious, rugged, no-nonsense tube of triumph handles the dirty work like a champ. Flexible enough to twist through campsite chaos, tough enough to face the horrors within, and long enough to keep your nose far from danger. It turns a stinky job into... well, a less stinky job. 5 stars for keeping the crap where it belongs—out of sight and out of smell. ... show more

  • Great quality
The quality of this product is great. The only complaint I have is that when you turn them to lock them in, they are very tight. If you don’t have strong hands, you probably will need the tool.

  • Heavy duty hoses
Nice set of hoses and coupler but does not have re-usable ends anymore.

  • Quality is great
⸻ The hoses and connections are well designed, with quality materials and precise fittings that ensure a secure and reliable setup. Everything assembled smoothly, and the overall construction suggests durability and long-term performance. A solid, well-executed product.

  • Buy the best!
Perfect for my park model as I have 2 gray tanks and 2 black tanks. Perfect for the Y to connect to both tanks. As for additional support, I used a 4 inch pvc pipe cut in half and angled downward to the drain. Others I camp with have used rain gutter. Better than all the other supports shown out there and the one's talked about here will last longer. Got to say that all the connections are air tight and well worth spending a little more than wanted too. Hoses are very sturdy, and flexible as one side stretched out and the other side compressed to fit drain. Would buy again! ... show more
