[wedged]

I did some work on the bed. Before, the only thing holding the sides at the back was the tailgate when closed with the chains. On a stock truck, the bed floor was wood and there were wood cross bars under the bed. The rear most one was through bolted to the bottom of the rear stake pockets. I put some box tube from side to side to hold it together. The rear most piece of tube has uprights that go up inside the stake pockets. I plug welded them inside the pockets. It made the rear bed sides a lot more stiff and stable now, even with tailgate off.
