Why does my RV not have a fuel hatch?

RV manufacturers build motorhome bodies on commercial truck chassis. The chassis maker provides a filler neck but no fuel hatch — and the RV body builder does not add one either. It is an industry-wide oversight.

Is The RV Fuel Vault a real fuel hatch or just a cap cover?

It is a full locking fuel hatch door that covers and secures the entire filler neck area — not just a cap replacement. It provides both the finished look of a factory fuel hatch and real keyed security.

The RV Fuel Vault fits Ford E-350, E-450, F-550, F-600, F53, Workhorse W22/W24, and Ram 5500 chassis. Use our Fitment Finder to confirm your exact vehicle.

How hard is the installation?

8-15 minutes with basic hand tools. No drilling, no cutting. Completely reversible.

Limited Lifetime Warranty against defects in material and workmanship plus a 30-day satisfaction guarantee.

The Problem

✖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
