I had a well worn out 68 shortbox. The scale guy yells 1.8 ton when I had it loaded with sand. It took all of that to plant it firmly down and I was probably lucky the wheels didn't fall off going over the Granville bridge in Vancouver. They drive good with weight on them. After unloading it was right back up to its usual height.

Driving that truck empty over the railroad tracks from work and it would really bounce around. Make sure your U-bolts holding the differential in are tight as mine was flopping loose.

My 66 with 8' box has new springs/shocks and still bounces around like you describe. It's just the nature of the beast I think. Are the front end components good?
