are you saying the truck was original with a diesel and 5.29 gears

most of the time those 6 speeds are direct drive as well, so that truck would have been all out pegd rpm wize, at some where "around" 53/63 mph peg out speed

not good for mpg in flat land!

if you have on board air and tools in the truck
taking the wheels/tires off the jeep "after its on the trailer" would lower the air drag "for the long drive". the jeep would drop nearly 9"/12"

if the truck has 24.5 rims you could go to 22.5 rims with lower profile tires to make space to lower the truck a little, possibly go to 19.5 rims but i don't know if it would clear the brake drums. as to if it whould make 3" of clearence for lowering the rig

maybe, maybe not
the gearing change would more than make up for the shorter tires.
but as stated realer thats a lot of work/cost to lower it.

maybe if theres a spacer in-between the box and the frame rail it would be better to lower the box closer to the frame, than try and lower the leaf springs???
