Reliable, Well-Designed Sewer Hose Kit That Just Works
Style: 15' Rhino Sewer Hose
This Camco RhinoFLEX 15-ft RV sewer hose kit is another example of why I continue to buy Camco products. Everything about it feels well thought out, solidly constructed, and designed specifically for real RV use. The hose is flexible yet durable, connects easily, and holds its shape without feeling flimsy or cheap.
The clear elbow fitting with the removable 4-in-1 adapter is especially useful. Being able to visually confirm when the tank is fully drained adds peace of mind and takes the guesswork out of the dumping process. Connections are secure, leak-free, and quick to set up and break down at the campsite.
After using it multiple times, I can say this kit simply works the way it should. It’s dependable, easy to handle, and offers excellent value for the quality you get. I would absolutely recommend this sewer hose kit to any RV owner looking for a reliable, no-nonsense solution that performs every time.

Clear elbow not detachable
Style: 15' Rhino Sewer Hose
Sewer hose is fine except the clear elbow is permanently attached and no removable.
Also shipped via USPS vs. UPS. USPS couldn't/wouldn't deliver so had to go to the Post office to pick it up.
