Fuel Theft Is Rising Again: How RV Owners Can Protect Their Tank

Fuel theft is back in the local news. Two reports from October 2026 show how quickly thieves move when fuel prices climb, and why an unlocked fuel door is an easy target for any vehicle with a big tank, including your motorhome.

In the News: Two Recent Fuel Theft Reports

Diesel siphoned from parked trucks in Ventura County, California

On October 21, 2026, *Overdrive* reported that suspects were caught siphoning diesel from the tanks of parked tractor-trailers in Ventura County, California. The story is a reminder that large tanks parked overnight are a prime target. Read the full story at Overdrive.

Community alert after fuel thefts in Wheeler County, Nebraska

On October 20, 2026, 10/11 NOW (KOLN) reported that the Wheeler County Sheriff's Office issued a community alert after multiple fuel thefts were reported. With gasoline and diesel prices on the rise, the sheriff's office asked people to protect their property and report suspicious activity. It also urged people not to approach or confront anyone suspected of a crime, and to note vehicle descriptions, license plate numbers and other details instead. Read the full story at 10/11 NOW.

Why This Matters for RV Owners

The thieves in these stories went after trucks and storage areas, but a motorhome checks every box they look for:

And theft is not the only risk. An open fill also invites tampering. Sugar, water or dirt in the tank can mean a tow and a costly repair. See what happens if someone puts sugar in your RV gas tank.

Where RV Fuel Theft Happens

How to Protect Your RV's Fuel

1. Lock the fill area, not just the cap. A locking gas cap only covers the cap and can be pried off. Compare the two in locking gas cap vs. locking fuel door.

2. Park in well-lit, visible spots when you can, and choose storage lots with cameras and gated access.

3. Check your fuel gauge before and after storage so you notice a loss right away.

4. Watch for signs of tampering, like scratches around the fuel door, fuel smell or drips under the coach.

5. Report suspicious activity without confronting anyone. Note vehicle descriptions and plates and call law enforcement.

Frequently Asked Questions

Is fuel theft increasing in 2026?

Local news reports in October 2026 point to new fuel theft cases. Thieves were reported siphoning diesel from parked tractor-trailers in Ventura County, California, and the Wheeler County Sheriff's Office in Nebraska issued a community alert after multiple fuel thefts, noting rising gas and diesel prices.

Can thieves siphon fuel from a motorhome?

Yes. Many motorhomes, including Class C coaches on the Ford E-350 and E-450 and gas Class A coaches on the Ford F53 and Workhorse chassis, have a fuel fill behind a fuel door with no lock. A thief can open it in seconds at a storage lot, campground or rest stop.

Is a locking gas cap enough to stop fuel theft?

A locking gas cap is better than nothing, but it only covers the cap and can be pried or broken off. A locking fuel door covers the whole fill area and is fastened with security screws, so there is no easy way to reach the cap.

What should I do if I see someone stealing fuel?

Do not approach or confront them. Note the vehicle description, license plate and any other details, and call local law enforcement. That is the same advice the Wheeler County Sheriff's Office gave in its October 2026 alert.
