Someone's Stealing Diesel from Your Reading Truck.
$500–$1,000 per incident • Exposed fuel cap • No factory protection
Reading builds world-class service bodies with locks on every compartment. But the Ford or Ram chassis underneath has a wide-open fuel cap. Thieves know this. The Work Truck Fuel Vault is the bolt-on locking fuel door that stops diesel theft on Reading-equipped work trucks.
Founders Edition pricing — starting at $139.95 (Save up to $60)

Why Thieves Target Reading Trucks
Reading trucks are high-value targets: full diesel tanks, expensive tools, and a completely unprotected fuel cap on the OEM chassis.
- Ford and Ram ship chassis cabs with zero fuel cap security
- Reading body locks protect tools — the fuel cap is wide open
- Thieves target Reading trucks knowing they carry full tanks and valuable equipment
- Siphoning takes 5 minutes or less — no noise, no forced entry
- Locking gas caps are defeated in seconds with basic pliers
- Fuel contamination from tampering can destroy injectors ($3,000–$8,000 repair)
Stop Fuel Theft on Your Reading Truck
The Work Truck Fuel Vault makes siphoning physically impossible. One bolt-on install protects your diesel for the life of the truck.
- Armored locking door covers the entire fuel filler area — not just the cap
- Tamper-resistant torx fasteners — no quick-remove with pliers
- Compatible with all Reading service body models
- Bolt-on in 8–15 minutes — no drilling, no body mods
- Purpose-built for Ford F-350–F-600, E-Series, F53 and Ram 3500–5500
- Pays for itself after preventing a single fuel theft event

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.
Where Reading Trucks Get Hit the Hardest
Active Jobsites
Reading trucks parked at construction sites overnight. Fuel gets siphoned while nobody is watching.
Open Yards
City and county Reading trucks in unfenced lots. Easy targets for organized fuel theft.
Remote Utility Sites
Reading CSV and utility bodies on remote power and telecom sites. No cameras, no guards, no protection.
Fleet Parking Lots
Reading-equipped fleet trucks parked together. One exposed fuel cap makes the whole fleet vulnerable.
Dealer Lots
New Reading upfits sitting on dealer lots with full demo tanks. Lock the fuel before delivery.
Overnight Parking
Hotel lots, truck stops, residential streets. Anywhere your Reading truck parks overnight is a risk.
Chassis Compatibility
Purpose-built for the most popular commercial chassis platforms in the industry.

Frequently Asked Questions
Why are Reading trucks targeted for fuel theft?
Reading-equipped trucks are high-value targets because they carry full diesel tanks and expensive tools. Thieves know the fuel cap on the Ford or Ram chassis is completely unprotected.
Does the Fuel Vault stop siphoning on Reading trucks?
Yes. The armored locking door covers the entire fuel filler area — cap, neck, and access point — making it physically impossible to insert a siphon hose.
Will it fit any Reading body model?
Yes. The Fuel Vault mounts to the Ford or Ram chassis, not the Reading body. Classic II, SL, CSV, Landscaper — all compatible.
How much does fuel theft cost per incident?
A typical siphoning event costs $500–$1,000+ in stolen diesel, plus downtime, missed jobs, and potential tank contamination.
Can I install it myself?
Yes. Bolt-on in 8–15 minutes with basic hand tools. No drilling or body modifications needed.
How much does it cost?
Founders Edition starts at $139.95 with free shipping. Pays for itself after preventing one theft.
Is there a warranty?
Yes — Limited Lifetime Warranty and 30-day money-back guarantee.
