What Class A motorhomes does The RV Fuel Vault fit?

The RV Fuel Vault fits Class A motorhomes built on Ford F53 and Workhorse W22/W24 chassis including Coachmen Encore and Mirada, Entegra Emblem and Vision, Fleetwood Bounder, Flair, Fortis, and Southwind, Forest River FR3 and Georgetown, Holiday Rambler Admiral and Vacationer, Jayco Alante and Precept, Newmar Bay Star, Thor Hurricane and Windsport, and Tiffin Open Road Allegro.

Do Class A motorhomes have exposed fuel caps?

Yes. Most Class A motorhomes on Ford F53 and Workhorse chassis have fully exposed gas caps on the driver side with no factory security or cover.

How is this different from a locking gas cap for a Class A RV?

Locking gas caps for Class A motorhomes are often ill-fitting because the F53 and Workhorse filler necks differ from standard automotive sizes. The RV Fuel Vault is a complete locking door engineered for these specific chassis.

How long does installation take on a Class A motorhome?

Installation takes 8 to 15 minutes with basic hand tools. No drilling or modifications required.

How does the RV Fuel Vault stop fuel theft on a Class A motorhome?

It places a keyed, virtually unbreakable door over the gas cap so a thief cannot reach the cap to siphon fuel or add contaminants. The cover is made from 3/16-inch fiber-filled polymer that resists prying and impact.

How much does a Class A motorhome fuel cap cover cost and where can I buy it?

Pricing starts at $139.95 (Founders Edition) for a single door and $279.95 for a set of two. You buy it directly at thervfuelvault.com with free U.S. shipping and a Limited Lifetime Warranty.
