hi Ken,
I'm sure you have already checked ride height, but also take a look at weight loading. A slight pull can sometimes be caused by a torsion bar loading imbalance offset by differential air in the rear bags. Start by checking the air pressure in each bag when your coach is at correct rear ride height. If they are not the same, then block the center of the rear at correct ride height, dump 15psi out of both bags and recheck front ride height. If that checks out ok then recheck tire pressure and even wear. Swap the front tires side to side and see if that helps. Start playing with differential camber only if all else checks out. Road crown is not consistent so it is hard to set the "right" amount of differential for that reason.

That is what I have now. Maximum EQUAL caster side to side and 0 camber on both sides. I was just looking for what to tweek a bit. This is just a slight pull that was not there before I started. I'll drive it some more on 4 lane and 2 lane roads before I make any adjustments.
I just wanted to know what to change if necessary.
