Stop showing up to the dump station missing a fitting or a support. The Camco 43075 RhinoFLEX Combo Kit packages the hose, elbow, adapter, supports, caps, and storage into a single ready-to-go bundle designed around a 20-foot heavy-duty sewer hose with 3-inch bayonet fittings. One box, one purchase, no scrambling.
The RhinoFLEX 43075 is Camco's answer to the piecemeal sewer hose problem. Instead of sourcing a hose here, a fitting there, and a support somewhere else, this kit delivers a coordinated system where every component is sized and designed to work together. The 20-foot hose length covers the majority of campsite hookup distances, and the included accessories handle every transition from your RV's termination valve to the campground's sewer inlet.
The hose is built on Camco's RhinoFLEX platform -- a reinforced, flexible sewer hose with a crush-resistant spiral that holds its shape under foot traffic and storage stress. The clear elbow lets you visually confirm a complete tank flush without guesswork, and the 4-in-1 sewer adapter means you are covered at virtually any dump station fitting configuration in North America.
Covers the majority of campsite distances from your RV's termination valve to the sewer inlet without extensions.
Transparent elbow lets you see when your tank is fully flushed -- no guessing, no mess from disconnecting too early.
Single adapter handles four common dump station inlet sizes so you are prepared for any campground configuration.
The storage box doubles as a sewer hose support, elevating the hose to maintain gravity flow toward the dump station.
Every component included in the 43075 kit is listed below. Nothing is sold separately or requires a separate order to make the kit functional at a standard campground hookup:
The RhinoFLEX hose uses a thick-wall construction with an internal reinforcing spiral coil. This keeps the hose from collapsing under its own weight when extended horizontally, which is critical for maintaining proper slope and avoiding low spots where waste can pool. The exterior is UV-resistant to handle repeated outdoor exposure across camping seasons.
Both ends of the hose terminate in Camco's 3-inch bayonet fitting -- the industry-standard connection for Class A, Class B, and Class C motorhomes and most towable RVs (fifth wheels, travel trailers, toy haulers). The bayonet design locks onto your RV's termination valve with a quarter-turn and releases cleanly without tools. No thread cross-contamination, no stripping.
The RV-side fitting connects directly to standard 3-inch termination valve outlets. The dump-station end connects to the clear elbow, which threads or push-fits onto the 4-in-1 adapter seated in the campground sewer inlet.
The 20-foot hose covers the large majority of campsite pull-through and back-in hookups. For extra-long sites or unusual campground layouts, RhinoFLEX 10 ft extension hoses (Camco part 39860 or similar) can be added using the same bayonet fitting system. The nesting supports and storage box are sized for the 20 ft hose coil -- extensions are stored separately.
Proper RV sewer drainage depends on a consistent downhill slope from the RV outlet to the dump station inlet. The nesting hose supports included in this kit are designed to be stepped at different heights, creating an even grade under the hose run. The dual-purpose storage box provides additional support height at the RV end or midpoint depending on site geometry. Using the supports every dump reduces hose stress, prevents waste pooling, and speeds drainage of both black and gray tanks.
