Before you go running off with a bunch of new problems, did you measure the bed height of both trucks to verify there is in fact a difference? Flipping the axles may be a solution, however remember this will raise the overall height of the trailer, so be careful you don't get it much above 13 feet or you will have a whole set of new issues. On our rig, we had a similar issue and the axles were already below the springs. We ended up lowering the rear suspension 2.5 inches and resolved the issue. The trailer still rides slightly high in the front, but this was as close as we could get and still keep the truck level, maintain 6" clearance between the trailer and bed-rails and keep the overall height at 13'2". There is no easy fix as both solutions are a lot of work. Thanks Detroit!
