Thanks Lakeroadster, you have done a lot of analysis on this. I am adding a receiver hitch in place of my rear cross member. I looked at your various c-notch stress studies and none seemed to match the CPP design. Any chance you can add one? I can send you the dimensions. I qualify as one of those who does not understand beam analysis. Dammit Jim, I'm a banker, not an engineer.

My goal is to keep the bed floor stock. There is about 1" of space between the frame and the bottom of the bed wood. Maybe welding two pieces of 1"x1" square tubing to the top of the frame will increase the vertical height? I do plan to weld the C-notch in place and possibly box the inside.

My truck will be multi-purpose, mostly cruising, hauling stuff from the lumber yard, maybe towing a car trailer or car, and the occasional vintage drag race.
