Why Fleetwood owners need it
Fleetwood Class A coaches carry big gas tanks on the Ford F53 chassis with the cap exposed on the driver side. The diesel Altitude adds an exposed DEF cap on top of that. The RV Fuel Vault locks those fill points behind a keyed, armored door engineered for the exact chassis.
- 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.
