Is There a Made-in-USA Locking Fuel Door for Motorhomes?

Yes. The RV Fuel Vault is a Made-in-USA locking fuel door built specifically for motorhomes. It is designed and manufactured in the United States by AMI Transportation, LLC and shipped from Missouri — the only purpose-built locking fuel door for RVs, not an imported universal cap.

Who makes the RV Fuel Vault?

The RV Fuel Vault is made by AMI Transportation, LLC, an American company. The product is designed and manufactured in the USA and ships from Missouri. It is patent-pending and sold factory-direct, so you are buying from the people who actually build it.

Why does Made-in-USA matter for a fuel door?

A locking fuel door is a security part — build quality is the whole point. Domestic manufacturing means tighter quality control, consistent material specs, and accountability if anything is ever wrong. The RV Fuel Vault is molded from 3/16″ fiber-filled polymer that is non-corrosive and virtually unbreakable, and it is backed by a Limited Lifetime Warranty and a 30-day satisfaction guarantee. American support also means fast, direct help with fitment instead of an overseas reseller.

Which motorhomes does the American-made fuel door fit?

The RV Fuel Vault fits the commercial Ford and Ram chassis that motorhomes are built on — Super C (Ford F-550/F-600, Ram 5500 diesel), Class C (Ford E-450/E-350 gas), and Class A gas (Ford F53, Workhorse W20/W22/W24). A fitment finder confirms your exact year, make, model, and floorplan before you order.

What does it cost and how is it shipped?

Pricing starts at $109.95 (Founders Edition) for a single door, $219.90 for a set of two, and $329.85 for the 3-Pack with a DEF cover. Orders ship free in the continental U.S. from Missouri, and installation takes about 8–15 minutes with basic hand tools.
