Energy Company Warns of Rising Rural Fuel Theft — What Every RV Owner Needs to Know

Sarasota, Fla. — Michlig Energy, a regional fuel supplier, issued a warning this week to rural customers about a surge in fuel theft. In their September 23 advisory, the company cited high fuel costs as the driving factor and urged farms, businesses, and other fuel users to take immediate security precautions.

The company's top recommendation? "Install locking caps on fuel tanks."

If you own a motorhome — especially a Super C, Class C, or Class A — you should be paying close attention. Rural fuel theft isn't just a problem for farms and businesses anymore. RV owners face the same threat, and in many cases, they're even more vulnerable.

Most motorhomes leave the factory with completely exposed fuel caps. No door, no lock, no protection at all. If you store your rig on a rural property, park it at a campground, or leave it in an RV park for extended periods, you're leaving hundreds of gallons of diesel or gas completely unsecured. As Michlig Energy noted in their warning, "Even the theft of a few hundred gallons from a farm or business can quickly add up to thousands of dollars in losses." The same applies to your RV.

A typical Super C motorhome carries 75–100 gallons of diesel. At today's prices, that's $300–$500 sitting in your tank with nothing protecting it. DEF tanks add another $50–$100. For dual-tank rigs, you could be looking at $600–$1,000 or more in exposed fuel. And unlike a farm's bulk tank, your RV is mobile — making it a target wherever you park.

Michlig Energy's security recommendations read like a checklist for RV owners who don't want to become the next victim. The energy company advised customers to install locking caps, use security cameras, keep fuel tanks out of sight, track usage closely, and improve lighting around fuel storage areas. All of these strategies apply to motorhomes. But here's the problem: a locking fuel cap alone isn't enough for an RV.

RVs are parked in unsecured, semi-public spaces — campgrounds, Walmart lots, storage facilities, and roadside rest areas. A determined thief with a cordless drill can remove your fuel door screws in under 60 seconds, pull the entire factory housing, and drain your tank in minutes. Once the housing is off, your locking cap is sitting on the ground next to them. A real locking fuel door — one that bolts over the factory housing and secures with anti-tamper screws and a keyed lock — is the only way to truly protect a motorhome's fuel system.

The RV Fuel Vault was designed for exactly this scenario. It replaces the exposed factory fuel-cap area with a rugged, locking, factory-finished door that protects against theft, siphoning, contamination, and tampering. Every unit is manufactured in the United States and fits Ford E-Series, Ford F-53, Workhorse, Ford F-550/F-600, RAM 5500, and Freightliner S2RV chassis — covering the vast majority of Super C, Class C, and Class A motorhomes on the road today.

Unlike aftermarket chrome fuel doors or universal-fit accessories, The RV Fuel Vault was purpose-built for these specific chassis. It installs in 8–15 minutes with basic hand tools, uses anti-tamper security screws that can't be removed with a standard drill bit, and includes a keyed-different lock (not the universal CH751 key that opens half the RVs at the campground). Once installed, it looks like it came from the factory — because it was engineered to match the OEM finish and blend seamlessly with your coach.

Michlig Energy's warning underscores a problem that's only getting worse: fuel is expensive, theft is rising, and exposed tanks are easy targets. Farms and businesses are taking action. RV owners should too. A locking fuel door isn't just about preventing theft — it's about avoiding contamination (sugar, water, debris), protecting your DEF system, and eliminating the check-engine light issues that come with an improperly sealed fuel cap.

If you're storing your RV on rural property, parking it at campgrounds, or leaving it unattended for days or weeks at a time, your fuel system is vulnerable. The good news is that protecting it takes less time than an oil change and costs a fraction of what you'd lose in a single theft.

“When a major energy supplier tells rural customers to lock their fuel tanks, RV owners should be listening. Most motorhomes have zero fuel security straight from the factory. That was acceptable when diesel was cheap and theft was rare. Today, it's a liability you can't afford to ignore.”
