the problem is in the left rear of the truck, next time you see a transport truck look at the way the chevy,s are tie down. i work for a chevy dealership as an auto body tech and a few years ago we got paid by gm to correct the tweak on the frame. the problem is these truck are tied down on the front, and only on the left rear, and they actually twist the frame down a bit from the backside of the cab.
