This Camco Rhino 28-Gallon Waste Holding Tank is the durable, everything-you-need tote tank kit to fill, empty, clean, store and tow your tote tank when you’re too far away from a dump station to use a sewer hose. This RV waste tote tank is rugged, heavy-duty, and designed with the ease of use in mind. Everything from the interior to the exterior to the accessories included make a dirty job as simple and straightforward as possible.
Constructed of durable blow-molded, UV stabilized HDPE that won’t leak or deteriorate in the sun. With zinc-plated hardware, rust and corrosion are prevented. The inside of the tote tank is smooth so that it doesn’t trap odors or debris, and is sloped toward the drain hole, making it easy to empty. The handle is oversized and durable, allowing you to pull or tow the tote tank without worry. The bottom of the tote tank features an integrated ladder hook, allowing you to hang the tank on your RV’s ladder when it is empty, and tie-down grooves to hold it in place with straps. This ready-to-use kit includes everything needed to transport waste from your RV or trailer to a dump station.
