The Only Locking Fuel Door Purpose-Built for Motorhomes
Search everywhere \u2014 Amazon, RV parts stores, dealer accessories, aftermarket catalogs. You will not find another locking fuel door designed for motorhomes. Because The RV Fuel Vault is the first and only one ever made. Every car, truck, and SUV has a fuel door. Motorhomes never did \u2014 until now.
The Problem
- ✖Every car, truck, and SUV you have ever owned has a fuel door. Your $150,000+ motorhome does not.
- ✖No RV manufacturer has ever included a locking fuel door — the cap is completely exposed from the factory
- ✖No aftermarket company ever built one either — until The RV Fuel Vault
- ✖Locking gas caps are not fuel doors — they protect only the cap and are easily defeated
- ✖Universal fuel doors from auto parts stores do not fit motorhome chassis dimensions
- ✖Your fuel cap is the single most vulnerable access point on your entire motorhome
