I know this isn't a very "clean" solution,but have you tried adding some weight-maybe 200-300 lbs to the rear?Maybe the shocks have to be squatting a little more to get into the range where they dampen better.These vehicles have to be sprung so "heavy" to be able to carry and tow the rated loads.The extra weight of the hitch helped some,why don't you just test another 200 lbs.Cat litter containers will hold about 40-50 lbs of water.
I had a 86 Toyota truck that rode like a buckboard.With 300 lbs of water in the bed(about 30 1 gal milk jugs) it rode much better.
For the sharpness over bumps I would drop the tire pressure to the lowest level the manual allows(I don't have one yet,so I should probably butt out,but...).I don't like the move to bigger wheels on trucks,it increases the weight,and decreases the sidewall height.This takes a toll on the ride comfort;maybe it sways less,since there is less flexy sidewall,but...I'll take the comfort.
What wheel-tire size did the trucks you drove have?You have 18" and 265/70 which has the almost the same height sidewall as the XE 245/75 17",so it shouldn't matter.You don't have offroad do you?I would guess not
since you were concerned with mpg.
Well,wish I could be more help,these are half assed potential cures.Charlie PS Dealers used to drop the tire pressure so soften the ride on their demos.Kinda dangerous,so they probably don't do it any more.
