Wow, those are definately 4x4 alignment specs. The ones that I used were
way more performance oriented. However, your RF camber before measurement
of-1.5 is what I'm set at now. =P

So it goes by tire height? or diameter? Also, most tire manaucaturers have
on their websites something that lists the revs per mile of that specific
tire size.

That's quite a trip you've got planned there! Hope it all goes well for you
and the new rims/tires make the trip more comfortable. Just remember to
retorque twice at 50 mile intervals.
