Perhaps an airride system off another truck would work. Generally they are less harsh then spring ride. More expensive than staying with springs.Some folks just cut the frame and weld used cutoff suspension in place would also be a way to stretch the frame if you wanted to add a sleeper. Longer wheelbase would most likely improve ride as well. Newer cuttoff suspension and axles may also give you the option of a higher gear ratio since you won't be hauling heavy loads. Higher mph possible fuel savings. example 69 frieghtliner 671, 10 speed 4:11 rears,71 freightliner 8V71 13 speed 4:33 rears, 73 GMC 8V71 13speed 4:11 rears compare to the truck I'm running now with 3:25 rears but it develops twice the torque as the old DD. rpm 1550 at 75 vs 71 at 2100 with the older trucks.
