Fleet managers
How do I protect take-home and job-site work trucks from fuel theft overnight?
By The Work Truck Fuel Vault, Sarasota, Florida · Updated October 2026
Short answer
Lock the fill so the tank can’t be reached, no matter where the truck is parked. Take-home and job-site trucks can’t rely on yard fences or cameras, so a keyed armored fuel door is the protection that travels with the truck.
Overnight habits
- 1Install a locking fuel door on every take-home unit first.
- 2Park fuel-side toward the house, wall, or other equipment.
- 3Fuel in the morning when practical.
- 4Report fuel-level drops the same day.
Why they’re targeted
A lettered work truck parked on a residential street or an unlit job site is an obvious, unguarded fuel source.
