Motorhome Fuel Door — The Part the Factory Forgot
Cars have fuel doors. Trucks have fuel doors. Your motorhome should too. The RV Fuel Vault is the first locking fuel door purpose-built for motorhomes.

Why a Locking Gas Cap Is Not Enough
- ✖Motorhomes are the only vehicles on the road without a proper fuel door
- ✖Every car and truck has a fuel door — but your $100K+ motorhome does not
- ✖RV manufacturers build bodies on commercial chassis but never add a fuel door
- ✖Without a fuel door, your fuel system is exposed to theft, contamination, and weather
- ✖It is an industry-wide oversight that affects every Class A, Class C, and Super C

- Factory-finished look that matches the quality of your motorhome
- Tamper-resistant keyed lock secures your fuel system
- Fits Class A, Class C, and Super C across all major chassis
