Quick Question, any info would help, My 04 F250 Crewcab 4X4, I installed a Pro Comp 2.5" leveling kit on the front (new leaf springs), with shocks & U-bolts, and it looks great but my rear end sits about .5 to 1" lower now, it has the camper package installed, would it be best to swap out the rear 1-7/8 rear blocks with 2.5" or an add a leaf, I do pull a camper, and was thinking rear air bags, after reading the forums it seems i could go either way, any experience on this and what would be the best for handling...Many Thanks..
