The Camco Rhino RV Bumper Mount Tote Tank Holder secures your portable RV waste tank to 4" or 4-1/2" bumpers using a powder-coated steel frame and heavy-duty straps for dependable transport and storage.

Whether you camp for a weekend or live on the road, keeping your portable holding tank stable and out of the way matters. This Rhino bumper mount was created to attach tote tanks to RV bumpers without requiring a ladder, offering a low-profile, rugged mounting option that resists corrosion and vibration. It accommodates all four Rhino tote tank volumes and many other brands, so you get a flexible solution that fits most setups.

How does this holder keep a tote tank secure while driving?

The holder combines a rigid powder-coated steel frame with zinc-plated hardware and two polyester cam straps to lock the tank in place. The frame cradles the tank while the straps cinch tight, minimizing movement on bumpy roads.

• Powder-coated steel resists chips and rust for long-term strength.
• Zinc-coated bolts and hardware reduce corrosion risk near road spray.
• Two polyester cam straps provide adjustable, high-tension security.
• Designed to hold tanks snugly to reduce rattling and shifting.

Will this fit my RV bumper and tote tank?

This mount is engineered to attach to standard 4-inch and 4-1/2-inch round RV bumpers and works with Rhino tote tanks in 15, 21, 28, and 36 gallon sizes. It also accepts the majority of other portable waste tanks with similar footprint dimensions.

• Compatible with both 4" and 4-1/2" round bumpers.
• Holds all four Rhino tote capacities (15–36 gallons).
• Likely compatible with many third-party portable tanks of comparable size.
• Simple mounting points allow installation without ladder access.

How durable is the mount for long-term outdoor use?

Built for camping conditions, the mount’s powder-coat finish shields the underlying steel from moisture and abrasion. Zinc-plated fasteners and rugged webbing straps round out the construction so the assembly endures road grime and seasonal storage.

• Powder-coated finish prevents rust and surface wear.
• Zinc-coated hardware offers additional corrosion resistance.
• Heavy-gauge steel provides structural integrity under load.
• Polyester cam straps withstand UV exposure and repeated tensioning.

How easy is installation and removal?

Installation is straightforward and designed with practicality in mind: attach the mount to the bumper, position the tote, then secure the cam straps. Removal is equally simple, making it convenient for storage or when you don’t need the tank mounted.

• No ladder required—mounted at bumper level for easy access.
• Basic tools and included hardware complete the installation.
• Cam straps allow quick tightening and fast release when needed.
• Lightweight assembly for manageable handling during install/removal.
