Frequently Asked Questions
Can this tank hold both gray and black water?
Yes — the Silverback 15-Gallon is designed to safely transport both gray and black water waste.
Is this tank big enough for my RV?
The 15-gallon size is purpose-built for smaller holding tank setups — solo travelers, weekend campers, Class B vans, and pop-up trailers. If you have a larger RV or bigger holding tanks, Valterra's Silverback lineup also offers larger configurations (up to 36 gallons) in both 2-wheel and 4-wheel designs.
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 or blowouts, even on hot pavement or rough terrain.
Can I tow this behind my vehicle?
Yes — the included heavy-duty tow strap allows for low-speed towing behind your tow vehicle in addition to manual maneuvering with the integrated handle.
How do I know when the tank is full without opening it?
The ClearView fill window lets you visually check your fill level at any time, without opening the cap or guessing.
How do I store this while traveling?
The built-in ladder mount lets you hook the tank securely to your RV's rear ladder for space-saving storage, and dual strap grooves allow for extra security with ratchet straps (sold separately).
What's included in the box?
The tank ships complete with cap, adapter, hose, and tow strap — ready to use out of the box.
