Your Fuel Caps Are Completely Unprotected
Super C, Class C, and Class A motorhomes are built on commercial truck chassis where fuel cap covers were never included. That means your fuel caps have no lock, no seal, and no finished look — straight from the factory.
Standard fuel cap — no lock, no cover, no protection.
No Lock on Your Fuel
Standard RV fuel caps have zero security — anyone can open them. A keyed lock adds the protection the factory left out.
Open to the Elements
Rain, road spray, and debris can work their way into an unprotected fuel fill. A sealed cover keeps your fuel system clean.
Preventable Maintenance Bills
Moisture and contaminants in your fuel system lead to costly repairs. A simple cover is the easiest preventive step you can take.
Unfinished Factory Look
Bare fuel caps look out of place on a $200K+ motorhome. The RV Fuel Vault gives your rig the production-complete finish it deserves.
Engineered Protection. Factory-Finished Look.
The RV Fuel Vault is the first product specifically designed to cover, lock, and protect the exposed fuel caps on your motorhome — while giving your RV a clean, production-complete appearance.
