The Locking Fuel Door Built for RVs
Most locking fuel doors are made for pickups and cars — not motorhomes. The RV Fuel Vault is a locking fuel door for RV and motorhome chassis, engineered for exact fit on Ford E-350, E-450, F-550, F-600, F53, Workhorse, and Ram 5500. It seals your exposed fuel cap behind a keyed door so siphoning, contamination, and tampering are stopped cold.
With diesel now over $6 a gallon, a single full tank can hold hundreds of dollars in exposed fuel. See why your RV fuel tank is a bigger target than ever and how a locking fuel door shuts that risk down. You can also compare it to a standard anti-theft fuel cap cover.
What is a locking fuel door for an RV?
A locking fuel door for an RV is a keyed cover that mounts over your motorhome’s exposed fuel filler and cap, sealing it behind a hardened door. The RV Fuel Vault is a locking fuel door built specifically for RV and motorhome chassis, so it blocks siphoning, contamination, and tampering that a bare OEM cap cannot.
Do they make a locking fuel door for RV motorhomes specifically?
Yes. Most locking fuel doors are made for pickups and cars and do not fit motorhome filler necks. The RV Fuel Vault is a locking fuel door made for RV chassis — Ford E-350, E-450, F-550, F-600, F53, Workhorse, and Ram 5500 — covering nearly every Super C, Class C, and Class A motorhome.
Does an RV locking fuel door stop diesel theft?
Yes. With diesel above $6 a gallon, a full tank can hold hundreds of dollars in exposed fuel. An RV locking fuel door seals the filler behind a keyed door so a siphon hose cannot reach the cap, stopping the most common form of RV fuel theft.
