This is the RDS 63 Gallon Wedge Diesel Auxiliary Tank (Scratch / Dent).

These tanks have scratches, dents or weld burns. These are not pristine tanks! These aluminum fuel tanks are sold "AS IS". There is no warranty and no returns. All of these tanks have been tested to ensure there are no leaks or structural integrity concerns. All of these particular tanks are sold "sight unseen". They typically have dents, scratches or weld burns. We do not have pictures of each tank and we cannot provide those to you. The pictures that you see above are strictly EXAMPLES of types of issues that a tank may have. These are NOT the exact pictures of the tank that you would receive.

An Ideal option for fifth wheel applications. The tank has the clearance needed for a fifth wheel, while still adding additional fuel capacity to your factory tank. Auxiliary tanks can be used as additional capacity for a factory tank with the use of an RDS diesel install kit. Shop for better fuel prices with this increased range. All tanks Meet DOT standards.

Diesel Install kits are optionally available. Not intended to be used for gasoline. Made in the U.S.A.

NOTE: For safety reasons, the filler neck of these tanks prevents them from being overfilled. Actual usable tank capacity is about 95% of the total advertised gallons.
