@plasticsnaks or anyone else

I just dropped the truck off at the alignment place. The tech I spoke with warned me against going higher on the caster saying it could cause issues with the drive train and how it handles on and Offroad. I understand that the turning radius will be affected somewhat but would going from 4 to 5 degree of caster really affect the drivetrain and how it acts when 4x4 is engaged?

I told him lets see what they can get out of moving it forward a bit. It doesn't rub at all when moving the tires to and fro while standing still, only when in motion and at a sharp turn.

He was really pushing doing the BMC which I just don't want to do.
