I bought this truck used, 2nd owner local from dealer. It had some rocker panel rust then. Last year I removed the bed to fix the rocker panels, and cab corners. That's when I really noticed the frame rust. Finished body work ,cleaned rust off frame in rear under the bed, replaced 1 shock bracket. As of now the frame behind the right front tire where it is tube steel has rotted away at the bottom, so I have parked the truck with only 156000 miles. I didn't see it rusted out 3000 miles ago when I changed the oil. I had already got the truck ready to repaint it from front to rear. Glad I hadn't bought the paint yet.
