I know I'm bringing up an old thread, but it is a fun one. Last week I made another salvage run with batteries and two large motors. I pushed/stacked the batteries as far forward as possible and kept loading. Filled the bed. I ended up having 2526 pounds in the back. Most of the weight was in the front, so it didn't squat down so much. But driving was another thing. I was stable at 55mph, but approach 60mph and the back end would sway like a whipping trailer.
