Your axle loads are not consistent with the reported tongue weight.
The axle load data indicate a tongue weight of about 600# versus the 820# from direct measurement.
I'm guessing the 820# value is closer to correct.
A tongue weight of 820#, with no WD applied, should have caused a load of about 330# to be removed from the steer axle and a load of about 1150# to be added to the drive axle.
I think a re-weigh is in order.

I was working in Kilograms and my son was in and out of the truck; he's about 30 pounds, which is why some of the weights are a bit off. The scale rounds to the closest 10 kgs, which is almost 25 pounds. The reason the WD hitch is only redistributing about half is that's what I thought GM wanted. I am readjusting.
I was merely pointing out to the OP that with a truck his size and minimal tongue weight acting on it; not a lot changes from loaded to unloaded.
