When I had my 399, it was with a long bed truck and factory 5th wheel prep with a traditional 5th wheel hitch. If I did a 90 turn, I would have 3 - 4" clearance between cab and trailer. If that would have been a short bed, there would have been some damage. I would def look into a slider hitch with a short bed truck...or look for a long bed truck if your considering that as an option.
