    On the road again!

    Posted by David Janowitz on 10th Jun 2013

    When I traded my last truck the tank in the bed went with it. ATTA offered the quality I needed with a feature I wanted; Freedom Fill. This was no short installation, and not for a rookie, but the end result is worth it! The tank and fill systems are first class across the board. I would highly recommend their products. Well Done!!
