Why a Locking Gas Cap Is Not Enough

  • Motorhomes are the only vehicles on the road without a proper fuel hatch
  • Without a fuel hatch, your filler neck is exposed to theft, siphoning, contamination, and weather
  • Generic fuel hatches from auto stores were designed for cars and trucks — not RV filler geometry
  • An exposed fuel cap on a $100K+ motorhome looks unfinished and invites unwanted attention
  • RV manufacturers do not offer a fuel hatch option from the factory

Why a Locking Fuel Door Beats a Locking Gas Cap

  • The first locking fuel hatch purpose-built for motorhome filler necks
  • Factory-finished look — your rig finally has the fuel hatch it deserves
  • Tamper-resistant keyed lock secures your fuel against theft and contamination
  • High-strength 3/16 inch fiber-filled polymer — built for the road, not a showroom
  • Bolt-on in 8-15 minutes — no drilling, no cutting, no modifications
  • Fits Ford E-350, E-450, F-550, F-600, F53, Workhorse, and Ram 5500 chassis
