Description
Valterra Silverback 36-Gallon Tote Tank – Gray & Black Water Waste Transport
Built for full-timers and extended-stay campers who need maximum capacity in a manageable package, the Valterra Silverback 36-Gallon Portable Waste Holding Tank is one of the highest-volume 2-wheel tote tanks available — and unlike competitors, the number on the box matches the actual volume in the tank. This heavy-duty, blow-molded tote tank lets you dump both gray and black water at the nearest station without moving your entire RV, cutting down on frequent dump-station trips during longer stays.
The 2-wheel design keeps the form factor compact for truck bed storage and tight spaces, while the ergonomic Tow-N-Pull handle provides a full-hand grip for comfortable pulling even at maximum weight. Strategic axle placement reduces the weight you lift by 25%, and a zero-lift design lets you empty the tank on flat ground without hoisting it. Featuring the industry's most robust handle and wheel assembly, this 36-gallon tank is engineered to withstand the weight of a full load on any campground surface without mechanical failure.

Frequently Asked Questions
Can this tank hold both gray and black water?
Yes — the Silverback 36-Gallon is designed to safely transport both gray and black water waste.
Is this tank actually 36 gallons, or is that an inflated marketing number?
Unlike many competing tanks, Valterra confirms the number on the box matches the actual volume in the tank — this is one of the highest-volume 2-wheel tote tanks available at true 36-gallon capacity.
Is this too heavy to pull when full?
At full capacity, this is a heavy-duty tank, but the ergonomic Tow-N-Pull handle, strategic axle placement (reducing lifted weight by 25%), and zero-lift emptying design are specifically engineered to make hauling a full 36-gallon load manageable.
What hitch sizes does this fit?
The tow mechanism is compatible with 1-7/8", 2", and up to 2-5/16" hitch balls — covering the vast majority of standard tow vehicles.
Do the wheels ever go flat?
No — the Silverback uses airless rubber tires with reinforced fiberglass wheels, so there's no air pressure to maintain and no risk of flats, even on hot pavement or rough terrain.
Should I get the 2-wheel or 4-wheel version of this 36-gallon tank?
The 2-wheel version keeps a more compact footprint for truck bed storage and tight spaces. If you dump multiple times per week as a full-timer and want maximum maneuverability with steerable front wheels, Valterra's 4-wheel 36-gallon version may be worth considering instead.
How do I clean the tank after dumping?
The 360° jet-spray cleanout port connects to any standard garden hose, driving high-powered water jets into every corner of the tank for a thorough rinse.
