Ok, here's where it ended up. I still need to do the drive straight part to let things settle:

I shimmed the frame mount based on trying to get the bar parallel to the lip on the cam. It seems as if I shimmed the truck side while others shimmed the trailer side. How do you check to see if shims should be added/removed:

It looks like the bar is not quite flat on the cam, but I don't know if there's anything I can tweak to deal with that:

I had to relocate the brake safety switch. How can I determine if the cable is too long?
