Locking RV Fuel Cap Cover — Security Meets Factory Finish
The RV Fuel Vault is the first locking fuel-door enclosure engineered for motorhomes. Beautiful factory-finished look with a tamper-resistant keyed lock built in.
Why a Locking Gas Cap Is Not Enough
- ✖Every motorhome ships with a completely exposed, unlocked fuel cap
- ✖There was no locking fuel-door enclosure designed for motorhomes — until now
- ✖Generic covers from auto parts stores do not fit RV commercial filler necks
- ✖Exposed fuel caps invite theft, contamination, and give your rig an unfinished look
- ✖RV manufacturers do not offer a locking fuel-door enclosure option
Why a Locking Fuel Door Beats a Locking Gas Cap
- The first locking fuel-door enclosure purpose-built for motorhome filler necks
- Factory-finished look — your rig finally looks production complete
- Tamper-resistant keyed lock built right into the cover
- High-strength fiber-filled polymer — UV-proof, weather-proof
- Bolt-on in 8-15 minutes — no drilling, no cutting
- Fits all major chassis: Ford E-350, E-450, F-550, F-600, F53, Workhorse, Ram 5500
