Your RV Fuel Cap Is Completely Exposed — Here's How to Cover It

## Your RV Fuel Cap Is Completely Exposed — Here's How to Cover It **If you can see your RV's gas cap from across a parking lot, so can everyone else.** Most motorhomes on Ford, Ram, and Workhorse chassis have completely exposed fuel caps — no cover, no door, no protection of any kind. This leaves your fuel system vulnerable to theft, contamination, and weather damage. An RV fuel cap cover is the simplest upgrade that makes the biggest difference in fuel security and appearance. ### Why Your RV Fuel Cap Needs a Cover - **Security:** An uncovered fuel cap is an open invitation for thieves. Siphoning a 50–100 gallon tank takes minutes and costs you $200–$500 in fuel. - **Contamination protection:** Without a cover, anyone can drop sugar, water, sand, or the wrong fluid into your tank. Engine repairs from contamination run $5,000–$15,000. - **Weather and road protection:** Rain, road spray, salt, and debris constantly hit your exposed filler neck. Over time this causes corrosion and seal failure. - **Appearance:** Every car and truck has a fuel door. Your $200K+ motorhome should too. ### What About a Locking Gas Cap? A locking gas cap only protects the cap opening itself. It can be pried off with basic tools in under a minute. It doesn't cover the filler neck area, doesn't prevent contamination around the seal, and doesn't improve the appearance of your rig. ### The Better Solution: The RV Fuel Vault **[The RV Fuel Vault](/#pre-order)** is a purpose-built fuel cap cover that goes beyond a simple cap replacement: - **Full enclosure** — covers the entire filler neck and cap area, not just the cap opening - **Tamper-resistant keyed lock** — real security, not just a twist-off cap - **3/16" fiber-filled polymer** — UV-stable, corrosion-proof, virtually unbreakable - **Factory-finished look** — transforms the ugly exposed cap into a clean, intentional design - **8–15 minute install** — bolt-on, no drilling, no modifications Fits Ford E-350, E-450, F-550, F-600, F53, Workhorse W22/W24, and Ram 5500 chassis — covering virtually every Super C, Class C, and Class A motorhome.
