Chevy RV Locking Fuel Door: Built for the Round Chevrolet Bezel
Class C and Super C motorhomes on Chevrolet chassis use a round factory fuel bezel with the cap sitting out in the open. The RV Fuel Vault Round door is the exact-fit, bolt-on locking enclosure made for it.
Why a Locking Gas Cap Is Not Enough
- ✖Chevy-chassis Class C and Super C coaches leave the factory with an exposed, unlocked fuel cap
- ✖Rectangular RV fuel doors built for Ford chassis do not fit the round Chevrolet bezel
- ✖An exposed cap invites fuel theft, siphoning and tank contamination at campgrounds and storage lots
- ✖A twist-off locking cap can be pried off in seconds and leaves the whole bezel exposed
Why a Locking Fuel Door Beats a Locking Gas Cap
- Exact fit for the round factory bezel on Chevrolet chassis, not a rectangular door forced to fit
- Tamper-resistant keyed lock secures the cap inside a heavy-duty enclosure
- Bolt-on in minutes with the included round-bezel security screws, no drilling
- 2-Pack doors are keyed alike, so one key opens both fuel ports on a Super C
- Optional lock dirt & dust cap keeps the keyway clean
- Designed and made in the USA, backed by a Limited Lifetime Warranty
