The Best RV-Specific Locking Fuel Door — Built for Motorhomes, Not Trucks
The RV Fuel Vault is the only locking fuel door engineered from the ground up for Super C, Class C, and Class A motorhomes. Factory-finished look. Real security. No compromises.
The Problem
- ✖Every motorhome leaves the factory with an exposed, unlocked fuel cap — no fuel door at all
- ✖Generic truck fuel doors and universal locking gas caps were never designed for RV filler neck geometry
- ✖Chrome accessories are cosmetic only — they look nice but offer zero real security
- ✖Fuel theft, siphoning, and contamination cost RV owners thousands every year
- ✖Your $100K-$500K motorhome deserves better than a bare plastic cap on the side
The RV Fuel Vault Solution
- The only locking fuel door purpose-built for motorhomes — not adapted from truck parts
- Factory-finished look eliminates the ugly exposed cap and completes your rig
- Tamper-resistant keyed lock stops fuel theft, siphoning, contamination, and vandalism

- Fits Ford E-350, E-450, F-550, F-600, F53, Workhorse W22/W24, and Ram 5500 chassis
