Hi John,
It is very important for caster to be the same on both sides. What is less critical is the amount of caster so long as it is in the range of 2.5 to 5 degrees and even on both sides. Since our coaches are all 35+ years old with who knows condition of all the front end components and who knows location of the factory attachment points, I don't think anyone should just dial in max camber by yanking the rear upper control arm bushings as far towards the center of the coach as possible and hope it is the same on both sides. If anything is amiss it won't be when you also set camber to zero on both sides. The turn plates are an important part of doing this right.

Quote: 2 since it does not seem to matter if caster is different on right or
left, and since the rotation plates are only to measure caster, we
should not need the plates if we just adjust for max.
I thought it totally matters that the caster was the same on both sides as that is what controls whether you will pull to one side.
