Camco Rhino 36-Gallon RV Tote Tank with No-Flat Wheels & Built-in Gate Valve (39006) Review (2026)

What this product is

The Camco Rhino 39006 is a portable waste holding tank with a 36-gallon capacity, the largest tote tank in Camco's Rhino lineup, built for RVers who camp without a direct sewer connection and need to transport waste to a dump station. It measures about 15-1/2 inches long by 25 inches wide by 46 inches tall and weighs approximately 45 pounds empty, which gives a sense of how much space it needs in a storage bay or truck bed even before it is filled. The tank is built from UV-stabilized, blow-molded HDPE plastic designed to resist cracking and degradation from repeated sun exposure over multiple camping seasons.

Wheels and towing

The tank rolls on large, heavy-duty no-flat wheels with bearings, which avoids the risk of a pneumatic tire going flat mid-trip to the dump station, and it includes a removable steel tow adapter so it can be towed slowly behind a truck or golf cart instead of pulled by hand like a suitcase. That towing option matters because a 36-gallon tank weighs several hundred pounds when full of wastewater, well beyond what most people can comfortably roll any distance by hand, especially over gravel or uneven campground roads. The interior is smooth and sloped toward the drain, which is meant to help it empty fully rather than trapping residue in corners.

Included accessories

The tank ships with a built-in gate valve for controlled emptying, a large carry handle, a tank rinser, an integrated ladder hook that clamps onto an RV or camper ladder for secure transport, and body grooves for strapping it down during travel. It also includes a 3-foot heavy-duty sewer hose with a swivel bayonet and lug fittings, a 15-inch female-to-female grey water hose, a clear elbow with a 4-in-1 adapter, a clear double bayonet elbow, three storage caps, and two rinse connection caps with lanyards, plus the removable steel tow adapter already mentioned. That is a fairly complete accessory set compared with tote tanks that ship as just the tank and a short hose.

Where it fits versus rivals

In its own portable waste tank comparison, this 36-gallon Rhino ranks first among six options, ahead of a 32-gallon Tote-n-stor competitor with a similar wheeled design and Camco's own smaller 21 and 28-gallon Rhino tanks, plus a comparable 32-gallon Tote-N-Stor tank from a different retailer. Its main edge is simply capacity, since fewer dump trips are needed per outing compared with the 28-gallon or smaller models in the same lineup, though that extra volume also means it is the heaviest and bulkiest option in the group to store, fill, and maneuver around a campsite.

Who should buy it

This tank fits boondockers, dry campers, and anyone parked without a sewer hookup who wants to minimize the number of dump station trips per outing, especially those who have a vehicle or golf cart available to tow it once full. Owners with limited storage bay space or who plan to move the tank by hand rather than towing it may be better served by one of Camco's smaller Rhino tote tanks, since 36 gallons full is genuinely heavy to push or pull any real distance across gravel or uneven campground roads without a tow vehicle to help.
