Locking Fuel Doors for Maryland Work Trucks
If your trucks work in Baltimore, Columbia, Germantown, or anywhere else in Maryland, their fuel caps are sitting completely exposed every night. The Work Truck Fuel Vault is an armored, locking fuel door that bolts over the filler area in about 15 minutes — no drilling.
