I have a '04 Dodge 3500 DRW 4x4 and a '87 Alpenlite 19 ft 5th wheel. I had the same issue as the OP. To compound the problem, the pin was too close to the trailer. The axles were flipped.
1 I installed a 5th Wheel King Pin Extender for 10" additional clearance.
2 I cut the spring hangers loose and added a 2"x4" subframe, welded to original frame.
3 Welded 2" longer spring hangers, with 1/4" wall 2"x2" square tubing spacer, to subframe. The hangers/tubing was gusseted to the subframe.
This gave me about 8 inches of additional lift. So far, I have about 1000 miles on this setup. It appears to be okay. on one occasion, at about 70 mph, I had a sway issue. I removed some weight from a tool box on the rear of the trailer, and have had no sway since. I will start a thread on this subject.
Everything I have read on this subject has said you want the trailer level, with a minimum of 4" clearance between the trailer and truck bed rails. I have read flipping the axles is okay. There are arguments against adding lift blocks.
This is my finished product, all work done at home.
Better call out the weight police to make sure your not over weight since adding all that extra steel!! Lol!
