I had an '89 Sub 3/4 ton 4 x 4 and the only way I could get it to ride comfortably was with a heavy load in it that compressed the springs and took the harshness out of the ride. I traded it for a 1992 1/2 ton model model. The '89 was just too tough on long trips when it was empty. I now have an '06 Suburban 1/2 ton 4 x 4 that is the best ride of any that I have owned.
