Reading Builds the Body. Who Protects the Fuel?
Compartments Locked ✓ • Cargo Secured ✓ • Fuel Cap Exposed ✗
Reading Truck builds world-class service bodies with locks on every door. But the Ford or Ram chassis underneath ships with a completely exposed fuel cap. The Work Truck Fuel Vault is the bolt-on locking fuel door that closes the last security gap on your Reading-equipped work truck.

The Blind Spot on Every Reading Truck
Reading service bodies are engineered for security and durability. But the fuel system on the chassis below? That's the OEM's responsibility — and they left it wide open.
- Ford and Ram chassis cabs ship with completely exposed, unlocked fuel caps
- Reading body locks protect tools and cargo — nothing protects the diesel
- Thieves target Reading-equipped trucks knowing they carry full tanks and valuable tools
- A single siphoning event costs $500–$1,000 in fuel plus job delays
- Locking gas caps are easily defeated with pliers in under 10 seconds
Complete the Security on Your Reading Truck
The Work Truck Fuel Vault is the security upgrade Reading trucks have been missing. Same bolt-on simplicity, same industrial build quality.
- Armored locking door covers the entire fuel filler area — cap, neck, and access point
- Compatible with all Reading service body models — no interference with body layout
- Bolt-on install in 8–15 minutes — no drilling, no cutting, no body mods
- Purpose-built for Ford F-350–F-600, E-Series, F53 and Ram 3500–5500 chassis
- High-strength UV-stable composite — built to outlast the truck
- 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 with Reading service bodies?
Yes. The Work Truck Fuel Vault mounts to the chassis fuel filler area, not the Reading body. It fits any Ford F-350 through F-600, E-Series, F53, or Ram 3500 through 5500 chassis under a Reading service body.
Will it interfere with Reading body compartments or doors?
No. The Fuel Vault installs at the fuel filler area near the cab. It does not interfere with any Reading side compartments, doors, or rear access. Your body layout stays exactly the same.
Which Reading models are compatible?
All of them — Classic II, SL Service Body, CSV Enclosed, Landscaper, and more. The Fuel Vault mounts to the Ford or Ram chassis, not the Reading body, so any Reading configuration on a compatible chassis works.
Why do I need a locking fuel door if my Reading body has locks?
Reading locks protect your tools and cargo. The fuel cap on the truck chassis is a completely separate issue — Ford and Ram chassis cabs ship with exposed, unlocked fuel caps. The Fuel Vault fills that gap.
Can I install it myself?
Yes. Basic hand tools, 8 to 15 minutes. No drilling, cutting, or modifications to the Reading body or the truck chassis.
What trucks are compatible?
Ford F-350, F-450, F-550, F-600 Chassis Cab, Ford E-350/E-450, Ford F53 Workhorse, and Ram 3500, 4500, 5500 Chassis Cab.
How much does it cost?
Founders Edition pricing starts at $99.95 with free shipping. Volume discounts for fleet and dealer orders.
Is there a warranty?
Yes — Limited Lifetime Warranty and a 30-day money-back guarantee.
