Thanks for the input. The front end of the truck is already much lower than the rear (why it was easy for me to initially think that someone had raised the rear.) With a couple hundred pounds the rear will level out. I think I will continue on the cattle panel route for making an aero cap. I've gotten good at bending the panel making tomato cages. If I am understanding all the info I have found and read above I want a 12 degree slope (relative to the ground) going back and a 22.5 degree angle from the back of the cab to the tail gate to mitigate crosswind effects. I'd like to do as little extra bending and shaping as possible so it looks like I will have three triangles. Perhaps I should draw on some of the pictures of the truck to get a good idea how it will eventually work, and do some trig to get the shapes correct.
