Does the RV Fuel Vault fit a Ford F53 Class A?

Yes. Gas Class A motorhomes on the Ford F53 and Workhorse chassis are covered. Confirm your exact year and floorplan in Find My Fit to get the right door and screws.

Does it fit diesel pushers?

Diesel pushers usually already have a hinged factory access door, so they are generally not a fit. Check Find My Fit for your coach.

Does it fit older Workhorse coaches?

Our fitment records go back to the 1990s, and the fill area on these chassis has changed little. Confirm your year in Find My Fit.

How long does it take?

8–15 minutes with hand tools or an impact driver. No drilling.

What about Class C coaches?

Class C motorhomes on the Ford E-350/E-450 are covered too — see the E-350 / E-450 fuel door replacement page.

Class A Gas

Ford F53 / Workhorse Class A Fuel Door Replacement

Why a Locking Gas Cap Is Not Enough

✖Gas Class A coaches like the Fleetwood Bounder and Flair and Tiffin Open Road Allegro ship with an exposed fuel cap
✖Thin factory fuel doors crack and the latches wear out
✖Dust on an exposed cap seal can trigger the Ford “Check Fuel Inlet” warning
✖Stored coaches with full tanks are siphoning targets
