Gulf Stream BT Cruiser Locking Fuel Cap Cover
Purpose-built for Gulf Stream BT Cruiser Class C motorhomes on Ford E-350 & E-450 chassis — every floorplan from the 5210 through the 5270.
The Problem
- ✖Your Gulf Stream BT Cruiser has a completely exposed, unlocked fuel cap sitting open to anyone at any campground or overnight stop
- ✖Generic aftermarket locking gas caps don’t thread properly onto the Ford E-350 or E-450 commercial filler necks
- ✖Chrome “truck” fuel doors are cosmetic only — no lock, no tamper resistance, and wrong geometry for an RV
- ✖Gas-engine Class C motorhomes are increasingly targeted for fuel theft at truck stops and boondocking spots
The Solution
- Precision-engineered for every Gulf Stream BT Cruiser floorplan — 5210, 5220, 5230, 5240, 5245 (E-350) and 5255, 5260, 5270 (E-450)
- Tamper-resistant keyed lock built into a 3/16″ fiber-filled polymer door — corrosion-proof and virtually unbreakable
- Bolt-on installation in 8–15 minutes with basic hand tools — zero modifications to your coach
- Single Door ($99.95) • Set of 2 ($199.95) • 3-Pack ($299.95) • Free U.S. shipping
