You are welcome.
By far the most important fix is the removal of the interaxle drive shaft.
With it installed the truck suffers from severe understeer and is pushed
forward through the turns. That's what causes the cupping and tire wear.
Without the driveshaft, the turning radius is reduced to 33 feet (in my
case, measured repeatedly in a paved parking lot). The manual calls out a
turning radius of 37 feet.
As far as I know, the A3 version has the same problem.
A good front end alignment is just "gravy".
Lowering the tire pressure in the rear will put more tread on the road for
an even wear.
More pressure in the front because 50 psi just isn't enough for the load, at
highway speed, anyway.
If you have any questions, let me know.
