Valterra Silverback 36-Gallon 4-Wheel Tote Tank – Gray & Black Water Waste Transport
The flagship of the Silverback line, the Valterra Silverback 36-Gallon 4-Wheel Portable Waste Holding Tank delivers maximum capacity and maximum maneuverability for full-timers and extended-stay RVers who dump multiple times per week. With a verified 35.91-gallon actual capacity, this tank delivers every gallon promised — unlike competitors whose labeled capacity doesn't match reality. Four airless rubber tires on reinforced fiberglass wheels provide a 180° turning radius for effortless navigation through tight campground lanes and dump station approaches.
The "Zero-Lift" 4-wheel design is a game-changer for large RVs, supporting the entire weight of the waste so you never have to lift a heavy tank onto a hitch. With steerable front wheels and a heavy-duty Tow-N-Pull handle, you can transport a full load (approximately 300 lbs) as easily as pulling a wagon. Combined with Valterra's legendary gate valve and hose quality — the same components trusted as OEM standard on millions of RVs — this is the ultimate sanitation upgrade for a full-time RV lifestyle.

Frequently Asked Questions
Can this tank hold both gray and black water?
Yes — the Silverback 36-Gallon 4-Wheel is designed to safely transport both gray and black water waste.
Is this really 36 gallons, or is that inflated?
Valterra confirms a verified actual capacity of 35.91 gallons — this tank delivers essentially every gallon promised, unlike many competing tanks with inflated labeled capacities.
Do I have to lift this tank when it's full?
No — the "Zero-Lift" 4-wheel design supports the entire weight of the waste on its own wheels, so you never have to hoist a heavy tank onto a hitch, even at a full ~300 lb load.
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.
Why choose this over the 2-wheel 36-gallon version?
The 4-wheel design offers steerable front wheels and a 180° turning radius for superior maneuverability, plus the Zero-Lift design eliminates hoisting — ideal for full-timers who dump frequently and want the easiest possible hauling experience at maximum capacity.
Do the wheels ever go flat?
No — the Silverback uses airless rubber tires with reinforced fiberglass wheels on all four wheels, so there's no air pressure to maintain and no risk of flats, even on hot pavement or rough terrain.
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.
Is this tank harder to store than the smaller models?
Yes — at 36 gallons with a 4-wheel steerable design, this is the largest-footprint model in the Silverback lineup. Make sure you have adequate storage space (truck bed, basement compartment, etc.) before purchasing.
