Features
This tank fits under most tonneau covers and doesn’t interfere with 5th wheel towing. Meets DOT standards for both diesel and bio-diesel, and bolts directly into the truck bed with integrated mounting tabs. Made in the USA.
NOTE: For safety reasons, the filler neck on RDS fuel tanks prevents them from being overfilled. Actual usable tank capacity is about 95% of the total advertised gallons due to fuel expansion in warmer climates.
