Do you have the Trailing Arm rear suspension? I’m assuming yes.
I had the same issue with my 79 C-10.
It had what my son liked to call “that old truck bounce”, whenever we went over a sizable bump, or through a dip in the road.
While I had everything apart with the brakes and suspension, I went ahead and bought Coil Over Shocks for the front and rear.
Problem solved. The ride is smooth, and the suspension is firm but not harsh.
What you describe sounds kinda like my 1-Ton Dually. Rides nice till I go over a seam in the road or bog pot hole. Then it feels like no suspension.
But then again that’s when it’s loaded it’s fine.
