ATG Upfits the Truck. Who Locks the Fuel Cap?
Body Upfitted ✓ • Equipment Installed ✓ • Fuel Cap Exposed ✗
Auto Truck Group delivers some of the largest fleet upfit programs in North America. But the Ford and Ram chassis underneath ship with a completely exposed fuel cap. The Work Truck Fuel Vault is the bolt-on locking fuel door that should be on every ATG upfit spec sheet.

The Spec Sheet Gap on ATG Upfits
ATG processes thousands of fleet trucks a year. Every body gets locked, every tool gets secured. But the chassis fuel cap? That's still the OEM's responsibility — and they left it wide open.
- Ford and Ram chassis cabs ship with completely exposed, unlocked fuel caps
- ATG upfits secure the body and equipment — the fuel system is a chassis-level gap
- Large fleet lots are prime targets for organized diesel theft operations
- A single siphoning event costs $500–$1,000 per truck — multiply that by 100+ trucks
- Locking gas caps fail against determined thieves — defeated in seconds with pliers
Add Fuel Security to Every ATG Upfit
The Work Truck Fuel Vault turns chassis-level fuel security into a standard upfit spec item. Same simplicity, same scale, same bolt-on approach.
- Armored locking door covers the entire fuel filler area — cap, neck, and access
- Compatible with every ATG upfit configuration — service bodies, platforms, specialty
- Bolt-on install in 8–15 minutes — easy to add during or after the upfit process
- Purpose-built for Ford F-350–F-600, E-Series, F53 and Ram 3500–5500
- Scales to fleet volume — pricing for 10, 100, or 1,000+ units
- Limited Lifetime Warranty and 30-day money-back guarantee
The Part The Factory Forgot
The Work Truck Fuel Vault is an armored, locking fuel door that covers the entire fuel access area on your work truck. No more exposed caps. No more easy targets.
Why Didn't This Exist Before?
Despite billions lost to fuel theft every year, nobody built a real solution for commercial work trucks. Here's why.
"Good Enough" Thinking
The industry defaulted to cheap aftermarket locking gas caps. A $15 key-locked cap was considered good enough — until thieves proved otherwise with a pair of pliers.
Upfitters Focus on the Body, Not the Cap
Manufacturers like Knapheide and Reading engineer every compartment lock on the service body — but the chassis fuel pocket belongs to Ford or Ram. Nobody owned the gap.
The Zero-Drill Engineering Problem
Consumer billet doors are made for flat pickup beds. The recessed fuel pocket on a commercial chassis is a completely different geometry — and drilling risks voiding the chassis warranty.
The Cost Was Just "Absorbed"
Fleets treated fuel theft like weather damage. A $500 siphoning hit got buried in operating expenses. Without a purpose-built product available, the problem was simply accepted.
The Work Truck Fuel Vault is the industry's first drop-in armored fuel door that uses existing factory mounting points. No drilling. No cutting. No warranty risk.

Frequently Asked Questions
Does the Fuel Vault fit trucks upfitted by Auto Truck Group?
Yes. The Work Truck Fuel Vault mounts to the chassis fuel filler area, not the upfitter body. It fits any Ford F-350 through F-600, E-Series, F53, or Ram 3500 through 5500 chassis that ATG has upfitted.
Will it interfere with the ATG upfit?
No. The Fuel Vault installs at the fuel filler area near the cab. ATG body modifications, compartments, and equipment remain completely unaffected.
Why does an ATG-upfitted truck need this?
ATG upfits focus on the body and equipment. The fuel cap is a chassis-level component — Ford and Ram ship every chassis cab with a completely exposed, unlocked fuel cap. The Fuel Vault addresses that factory gap.
Can ATG install these during the upfit process?
Absolutely. The Fuel Vault is designed to be added during or after the upfit process. 8–15 minutes, basic hand tools, no drilling. Many upfitters add it as a standard spec item.
