Why Winnebago owners need it
Winnebago is the name most people picture when they think “motorhome” — and like every coach on the Ford E-450 and F53 chassis, the gas cap is left exposed from the factory. The RV Fuel Vault bolts a keyed, armored door over it so you are not handing thieves an easy target at the campground or storage lot.
- Stops fuel theft & siphoning — a keyed, virtually unbreakable door over the cap.
- Prevents contamination — no more open access to add water, sugar, or the wrong fluid.
- Built tough — 3/16″ fiber-filled polymer that is non-corrosive and resists prying.
- Factory-finished look — covers the ugly exposed cap for a clean, finished appearance.
