RV Fuel Door — The Part the Factory Forgot
Every car and truck has a fuel door. Your motorhome does not. The RV Fuel Vault is the first locking fuel door purpose-built for RVs.
The Problem
- ✖Your motorhome is the only vehicle you own without a fuel door
- ✖An exposed fuel cap on a $100K+ motorhome looks unfinished
- ✖Without a fuel door, your filler neck is open to theft, siphoning, and contamination
- ✖There has never been a fuel door option for motorhomes — until now
- ✖RV manufacturers focus on the interior and overlook fuel system finishing
