Spec'd Correctly Before It Ships

Ordering the wrong auxiliary tank size or fuel system costs your fleet real downtime — a tank that doesn't fit your bed length or a transfer system that isn't programmed for your ECM means the truck sits. Tank Vault eliminates that risk with free pre-offer spec review. We verify your truck bed length, fuel system compatibility, and vehicle programming requirements before the order ships. Tell us your make, model year, and bed configuration — we confirm the right tank and fuel transfer setup so your truck stays on the road instead of waiting on a return freight claim.

Industrial-Grade .125 Aluminum Construction

Industrial-Grade .125 Aluminum Construction

The ATTA Extreme Wedge is built-to-spec from .125 gauge aluminum — heavy-gauge material that handles highway vibration, off-road conditions, and diesel fuel exposure without cracking or corroding over time. This is not a light-duty accessory tank. It's a field-proven auxiliary fuel system constructed to the same standards fleet operations demand from their stationary storage equipment. Four capacity tiers — 60, 78, 94, and 105 gallons — cover short-bed and long-bed configurations across Dodge, Ford, and GM diesel platforms. Larger models include dual fill necks with matching locking fuel caps for added security on job sites.

Hook Up Your Trailer Without Losing Sight

Hook Up Your Trailer Without Losing Sight

The wedge profile solves a specific problem for operators who tow gooseneck or fifth-wheel trailers: standard auxiliary tanks block your line of sight to the hitch during hookup. The ATTA Extreme Wedge maintains clear visibility so you can position your trailer without a spotter or repeated pull-ups. The low-profile design sits below the bed rail, keeping the truck's rear window open for towing visibility. Whether you're backing onto a flatbed trailer at a job site or connecting a gooseneck livestock hauler, this tank stays out of your sight line while adding significant diesel range to your route.

Fitment Guide

The Extreme Wedge tank is designed for full-size diesel trucks. Confirm your bed length and cab configuration before ordering.

  • Full-size Dodge, Ford, or GM diesel truck
  • 60 gallon model fits short or long bed; 78–105 gallon models require long bed
  • Tank length ranges from 60 to 68 inches depending on capacity selected

Applications

“Put a 94-gallon Extreme Wedge in our '24 Silverado long bed. The Freedom Fill system was programmed correctly out of the box — no ECM issues, no check engine lights. Hooking up our gooseneck flatbed is way easier now that I can actually see the hitch. Tank Vault confirmed my bed length and fuel system before I ordered, which saved me from what would've been a wrong-size return.”

Frequently Asked Questions

The Extreme Wedge tank comes in four sizes: 60 gallon (18"x18"x60"), 78 gallon (18"x24"x60"), 94 gallon (18"x30"x60"), and 105 gallon (18"x29"x68"). The 60-gallon fits short and long bed Ford, Dodge, and GM trucks; the 78, 94, and 105-gallon fit long bed models only. Note: short bed Dodge may require notching and may interfere with factory puck systems.
You must choose either the Freedom Fill Fuel System or the Push N Fuel System at checkout. The Freedom Fill is a computerized system that transfers diesel from the auxiliary tank to the factory tank when it reaches about 1/2 tank. If selecting Freedom Fill, you must also provide your vehicle's make and model year for proper programming.
The tank is constructed from .125 gauge aluminum and is fully baffled for stability. It is designed for diesel fuel only. The fill neck and cap add approximately 2.5 inches to the height, and hold-down tabs add about 1.5 inches to the width at the front and rear.
The Extreme Wedge fits full-size Dodge, Ford, and GM diesel trucks with long or short beds, depending on the size. The 60-gallon fits short and long beds; 78, 94, and 105-gallon fit long beds only. Short bed Dodge trucks may require notching and may conflict with factory puck systems. Always verify dimensions and bed type before purchasing.
Installation typically requires mechanical and electrical knowledge. The Freedom Fill system includes a complete installation kit with components, but professional installation is recommended to ensure proper fitment and function. No assembly of the tank itself is needed beyond mounting and connecting the fuel system.
Routine maintenance includes checking for leaks or damage, ensuring electrical connections to the fuel transfer system are secure, and keeping the fill neck and caps clean. Use only diesel fuel. Periodically inspect the aluminum for corrosion. No specific maintenance schedule is provided; refer to the Freedom Fill or Push N Fuel system manuals for pump care.
Returns and support are handled by the seller. The product data does not specify a return window or warranty terms, so contact the store for details. Note that the Freedom Fill system requires vehicle-specific programming, so ensure correct selection at checkout to avoid compatibility issues. Support can assist with installation questions.
This tank is for diesel truck owners who need extended range for towing or long hauls, especially those using gooseneck or 5th wheel trailers. The wedge design preserves rear visibility during hookup. It suits full-size Ford, Dodge, and GM diesel trucks, with sizes for both short and long beds. Ideal for heavy-duty work or travel.
