Jeff: I went by yesterday to check the truck. The guy actually lifted the bed with an additional crossmembers. The bed clears the rear whell frame hump, but as you see in the pictures, the fender is way high. I'll upload a link tomorros of the photos I took. The website you posted was right on the money about the three methods and lifting the bed was one. As I'm in Guatemala, shipping a bed might be a little problem. I appreciate any help on the matter to try to fix, if possible the problem.
thanks
