The Problem
- ✖Every Ford E-450 Class C motorhome leaves the factory with an exposed, unlocked gas cap

- ✖Fuel theft, siphoning, and contamination are real risks at campgrounds and overnight stops
- ✖Your $150,000+ motorhome looks unfinished with a bare plastic cap on the side
- ✖Ford does not offer a factory fuel door solution for E-450 chassis RVs
