Our Story

Born from the RV community, The RV Fuel Vault was created by fellow motorhome enthusiasts who recognized a critical vulnerability in Super C motorhomes built on Ford chassis.
After experiencing firsthand the anxiety of leaving exposed fuel caps unprotected at campgrounds, rest stops, and overnight parking, we set out to engineer a solution that was as rugged as the rigs it protects.
AMI Transportation, LLC brings years of experience in the transportation and RV industry to deliver a product you can trust. Every Fuel Vault is designed, tested, and built to the highest standards.
