Why does my motorhome have no fuel cover?

It is an industry-wide gap. Chassis makers provide a filler neck but no cover, and RV body builders do not add one. The RV Fuel Vault is the aftermarket solution the industry has been missing.

Is this just a gas cap replacement?

No. The RV Fuel Vault is a full locking fuel door/cover that encloses the entire filler neck area. It is far more than a cap — it provides both cosmetic finish and keyed security.

Why a Locking Gas Cap Is Not Enough

✖Every motorhome leaves the factory with zero fuel cover — just a bare, exposed cap
✖An uncovered fuel cap invites theft, siphoning, contamination, and weather damage
✖Universal fuel covers from auto parts stores do not fit RV commercial filler necks
✖Your motorhome looks incomplete without a proper fuel cover on the side
✖No RV manufacturer offers a fuel cover as a factory option
