RV Fuel Door Lock — Built-In Security, Factory-Finished Look
Stop looking for aftermarket locks. The RV Fuel Vault has a tamper-resistant keyed lock built into the fuel door — one product, one install, total protection.

The Problem
- ✖There is no factory fuel door to lock — your motorhome has no fuel door at all
- ✖Aftermarket fuel door locks require a fuel door first — which your RV does not have
- ✖Generic locking gas caps provide minimal security
- ✖Separate fuel doors and separate locks mean multiple products and mismatched parts
- ✖No one makes a fuel door WITH a lock for motorhomes — except us
