The Best RV Fuel Hatch in America — And the Only One Purpose-Built for Motorhomes
You have been searching for an RV fuel hatch — and you have probably noticed there is almost nothing out there. That is because no manufacturer ever built one specifically for motorhomes. Until now. The RV Fuel Vault is the first and only locking fuel hatch designed, engineered, and manufactured in the USA exclusively for Super C, Class C, and Class A motorhomes.
Why a Locking Gas Cap Is Not Enough
- ✖Your motorhome left the factory without a fuel hatch — the filler neck is completely exposed on the driver side
- ✖Every other vehicle you own has a fuel door. Your $150,000+ motorhome does not.
- ✖Generic aftermarket fuel caps and universal covers do not fit — they are not engineered for RV chassis
- ✖An exposed fuel cap invites theft, siphoning, contamination, and vandalism
- ✖Diesel costs $4-5/gallon — your 50-100 gallon tank is a $200-500 target with zero protection
- ✖Road grime, water, and debris collect around the filler neck every mile you drive
Why a Locking Fuel Door Beats a Locking Gas Cap
- The RV Fuel Vault is the only fuel hatch purpose-built for motorhome chassis — exact-fit, not universal
- Tamper-resistant keyed lock provides real security against fuel theft, siphoning, and contamination
- Patent-pending design that bolts on in 8-15 minutes — no drilling, cutting, or body modifications
- High-strength 3/16″ fiber-filled polymer — UV-resistant, corrosion-proof, built to last the life of your rig
- Factory-finished look that transforms the driver side from ugly exposed cap to clean, intentional design
- Engineered and proudly manufactured in Sarasota, Florida — 100% Made in USA
- Starting at $139.95 with free shipping and a Limited Lifetime Warranty

Factory-Finished Look
Transforms the driver side from an ugly exposed cap to a clean, purpose-built fuel hatch that looks like it belongs.
Seal Out Contaminants
Keeps water, road grime, dirt, and debris away from your filler neck — protecting your engine from costly damage.
