Locking Fuel Doors for Wisconsin Work Trucks
If your trucks work in Milwaukee, Madison, Green Bay, or anywhere else in Wisconsin, 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.

Who Needs This in Wisconsin
