Sarasota, Fla. — RV PRO has covered The RV Fuel Vault, the family-owned Sarasota, Fla. manufacturer of a patent-pending, heavy-duty, bolt-on locking enclosure engineered to protect the exposed fuel and DEF fill ports found on Super C, Class C and Class A motorhomes, as well as fifth-wheels and travel trailers with onboard fueling stations.
Many RVs leave the factory with fuel and DEF caps sitting in open exterior pockets or behind non-locking plastic flaps, leaving them exposed to siphoning, fuel theft, contamination and vandalism. Unlike a locking gas cap, which secures only the cap and leaves the filler neck and housing exposed, The RV Fuel Vault bolts over the factory filler-neck bezel and turns the open recess into a sealed, locked, factory-finished door, with the original factory fuel cap protected behind it.
Highlights covered in the article include:
- Construction: molded in the USA from a 3/16-inch fiber-filled, high-impact reinforced polymer that is UV-stabilized, chemically inert to fuel, DEF and road salts, and rated from -40°F to 220°F.
- Security: anti-tamper security screws and a weather-shielded keyed lock set, backed by the $500 No-Siphon Promise (reimbursing the owner’s insurance deductible up to $500 for registered doors).
- Installation: bolts on in 8 to 15 minutes with basic hand tools using the factory mounting pattern, with no drilling, cutting or bodywork, so factory vehicle warranties stay intact.
- Fitment: Ford E-350/E-450, F-550/F-600 and F-53; Chevrolet/GMC Express/Savana, Kodiak/TopKick and Silverado 4500–6500; Ram 5500; International; and Workhorse chassis, plus a Round door configuration for round fuel fillers on toy haulers and select GM-chassis RVs.
- Warranty: limited lifetime warranty against manufacturing defects and a 30-day satisfaction guarantee.
