Stop fuel theft on your E-Series or F53 rig. The RV Fuel Vault Large Door includes 12 tamper-resistant security screws. Single door engineered to fit Ford E350, E450, and F53 platforms. The RV Fuel Vault is the first heavy-duty, patent-pending locking fuel door purpose-built for RVs and motorhomes - including Class A, Class C, and Super C coaches on Ford, Ram, and Workhorse chassis. Most gas motorhomes ship from the factory with a completely exposed fuel cap and no protective door, leaving fuel systems open to theft, siphoning, water, and contamination. The RV Fuel Vault bolts on over the existing filler neck in about 8-15 minutes with basic hand tools - no drilling, cutting, or bodywork - adding a keyed, sealed, tamper-resistant door made from a proprietary High Impact Reinforced Material that will not crack, rust, or corrode like thin factory plastic or chrome alternatives. It is designed and made in the USA by AMI Transportation, LLC, ships from Sarasota, Florida, and is backed by a Limited Lifetime Warranty and the No-Siphon Promise. The company maintains one of the largest locking-fuel-door fitment databases in the RV industry, spanning dozens of brands and hundreds of floor plans.
