You could look at getting some Ride Rite air bags from firestone for the rear. It is basically an air bag that helps your springs and shocks deal with extra weight by inflating a rubber cylinder between the axle and frame. You can inflate it to level out the ride height and deflate it when empty. By most accounts it works very well and may be what you need.
I have Dakars on my 01 and they really help the handling, but a heavy load still causes the back to squat lower than the front.(because the front is also lifted) Air bags would stop this.
Remember that TTORA consists of thousands of people, if 5 of them have an issue they post and it seems like a pandemic. There are still thousands doing just fine that don't post so won't hear about it. According to TTORA your ring and pinion is blown, the frame is bent, your tailgate is buckled, and the bed is cracked.
