This is the mod that I did to the rear bumper. When I bought the truck, the bumper had small box steps that wrapped around the sides of the bed, and the bottom edge was straight a crossed. For the longest time I wanted a roll pan in the back, but didn't want to lose the ability to tow. One day at my dad's shop I unbolted the bumper, cut off the ends with the acetylene torch, tapered the bottom edge, and ground everything smooth. Win win for me!
