The Part the Factory Forgot

Chevy Super C Locking Fuel Door: For the Rebel, Verrado and Entourage Platform

Super C motorhomes on Chevy medium-duty chassis, like the Nexus Rebel on the C6500, have two round factory fuel bezels with the caps left out in the open. The RV Fuel Vault Round Door 2-Pack locks both, with one key.

Why a Locking Gas Cap Is Not Enough

  • ✖Chevy medium-duty Super C coaches leave the factory with exposed, unlocked caps in round bezels
  • ✖A Super C carries a big fuel load, which makes it a prime siphoning target
  • ✖Rectangular RV fuel doors built for Ford chassis do not fit the round GM bezel
  • ✖A locking gas cap can be pried off in seconds and leaves the bezel exposed

Why a Locking Fuel Door Beats a Locking Gas Cap

  • Exact fit for the round factory bezels on Chevy medium-duty Super C chassis
  • Round Door 2-Pack is keyed alike, so one key opens both fuel ports
  • Bolt-on with the included 10-piece round-bezel security screw pack, no drilling
  • Optional lock dirt & dust caps keep the keyways clean
  • Designed and made in the USA, backed by a Limited Lifetime Warranty
