Ford F-600 Locking Fuel Door — The Part the Factory Forgot

The only locking fuel-door enclosure purpose-built for Super C diesel motorhomes on the Ford F-600 chassis.

The RV Fuel Vault — Locking Fuel-Door Enclosure — locking fuel door for motorhomes

The Problem

  • The Ford F-600 is the newest Super C chassis — and it still ships with no fuel door
  • Exposed diesel and DEF caps on a $400K+ Super C is an inexcusable oversight
  • The F-600 higher GVWR means larger tanks and more fuel to protect
  • No factory or aftermarket fuel door solution existed for the F-600 until now
  • Generic truck accessories do not fit the F-600 Super C motorhome body

The RV Fuel Vault Solution

  • First-to-market locking fuel door for the Ford F-600 Super C platform
  • Factory-finished look — matches the premium quality of your F-600 build
  • Tamper-resistant keyed lock secures diesel fuel and DEF
  • High-strength fiber-filled polymer — UV-proof, weather-proof
  • Bolt-on in 8-15 minutes — no drilling, no cutting
  • Fits Thor Magnitude/Omni Super C, Entegra Accolade XL, and upcoming F-600 builds
