ATTA 45 Gallon Roll-Top Bedcover Auxiliary Diesel Tank AT45LRT

ATTA 45 Gallon Roll-Top Bedcover Auxiliary Diesel Tank AT45LRT

The AT45LRT from ATTA is a 45-gallon reverse auxiliary L-tank engineered for trucks equipped with Retrax or Roll’N’Lock canister-style bed covers.

 Its low-profile “L” shape allows the bottom portion of the tank to slide neatly beneath the canister, preserving both function and space. Built from .125 gauge aluminum with reinforced 3/16” tailgate-side hold-down tabs, this tank is designed for strength and stability. It won’t interfere with your bed cover’s drain system and comes standard with a locking fuel cap.

Ideal for long or short bed setups—just note that short bed Dodge trucks may require a notched version for proper fit.

Features

• Bed Cover Friendly Design
  Fits cleanly under canister-style bed covers without blocking drain hoses or access.

   

• Low-Profile “L” Shape
  A 7” tall lower section slides beneath the canister for a seamless fit and full bed use.

   

• Heavy-Duty Construction
  Made from .125 gauge aluminum with 3/16” hold-down tabs for long-term durability.
