I just ordered a set of Rancho RS9000X Nine-Speed adjustable shocks.
www.samsoffroad.com has them on sale right now.
These are
not adjustable LIFT shocks. They are an adjustable
stiffness shock. I run my truck from totally empty to putting 3000+ lbs in the bed. I think it would be much more comfortable for my unloaded driving (this truck is my daily driver) to adjust them for these extreme differences in load. I also ordered the cab mounted remote so I don't have to crawl under the truck to turn the adjusting wheels....
