Frequently Asked Questions
Can this tank hold both gray and black water?
Yes — the Silverback 28-Gallon 4-Wheel is designed to safely transport both gray and black water waste.
Why choose the 4-wheel version over the 2-wheel 28-gallon model?
The 4-wheel design offers a 180° turning radius for superior maneuverability in tight spaces — ideal if you frequently navigate narrow campground roads, crowded dump stations, or need to steer around obstacles like picnic tables and other RVs.
Does this come with everything I need, or do I need to buy extra parts?
It ships as a complete kit: the 28-gallon tank, 3' sewer hose, 3" rotating bayonet adapter, Silverback quick coupler, and two termination caps — ready to use right out of the box.
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.
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 — no guessing, no unreliable float bobbers.
Is the 4-wheel version harder to store than the 2-wheel model?
The 4-wheel design does have a slightly larger footprint than the 2-wheel version, so consider your storage space (truck bed, basement compartment, etc.) if storage room is limited — but the added maneuverability is a significant advantage for tight campground navigation.
