First let some air out of the tires, tires are the first line of defense against a bumpy ride, lol.
Recommended tire pressure is just that, recommended, it's your truck and your *** getting bounced around, YOU decide correct tire pressure.
Has the suspension been modified?
Or is it stock
Shocks keep the truck from bouncing when you hit a bump, while stiff shocks can cause a harsh ride, regular shocks won't they simply absorb the bump and then slowly release to keep the springs from continuing to bounce up and down from the weight of the vehicle.
Often pickups are over sprung on the back axle to compensate for carrying loads, so when empty you basically feel every bump since springs and shocks are topped out, add some weight in the back, just to try it out, then the shocks can work.
