Spec'd Correctly Before It Ships

Wrong bed length. Wrong fill system. Wrong vehicle programming. Any one of these mistakes means downtime, return freight, and a truck that can't work until the replacement arrives. Tank Vault eliminates that risk. Before your ATTA roll-top tank order processes, we verify your truck bed length, your fuel system selection, and — if you choose Freedom Fill — your vehicle make and model year for correct system programming. We don't ship until the configuration matches your truck. No guessing, no return freight claims, no wasted weeks waiting on a corrected order.

Extended Range Under Your Roll-Top Cover

Extended Range Under Your Roll-Top Cover

The ATTA auxiliary tank adds 45 or 72 gallons of diesel capacity without sacrificing bed cover functionality. The 45-gallon configuration fits short and long beds on Ford, Dodge, and GM with a single driver-side fill neck. The 72-gallon version provides dual fill necks on both driver and passenger sides for long-bed applications. At 14 inches tall, the tank sits low enough to maintain roll-top cover available. This is field-proven aluminum construction designed for diesel fuel in demanding work environments — construction sites, long-haul routes, and remote job locations where a fuel stop isn't always practical.

Fuel System Integration Built for Your Vehicle

Fuel System Integration Built for Your Vehicle

Every ATTA roll-top tank requires either the Freedom Fill or Push N Fuel System — and Tank Vault ensures you select the correct one at checkout. The Freedom Fill system is the most popular option: a complete installation kit programmed to your specific vehicle make and model year. It manages fuel transfer between the auxiliary tank and your OEM system automatically. Push N Fuel is the alternative for operators who prefer manual control. Both systems are designed for below-bed-rail diesel auxiliary installations. We don't let you skip this step — because an unprogrammed or incompatible fuel system creates the exact downtime scenario you're trying to avoid.
