Yeah the rear chamber is interesting, you would think with a solid axle there would be no chamber movement. I can see toe movement if ubolts were looses and had play (one side further forward then the other) but even this i wouldn't expect a change. I am no expert by any means and this could be perfectly normal but i do find it interesting for the reasons above...

I could see either one of those effecting camber but what I am trying to understand is. Assuming this was the same day visit, how does the rear chamber before change on the after? Just seems odd, I would be asking the alignment shop how that is possible.. Maybe even questioning their machine.

Hopefully you didn't actually pay for a 4-wheel alignment since there is nothing to align in the rear... Maybe the tech just didn't setup the system for the rear and they are irrelevant readings?
Easy check is to support rear axle and just grab the tire and wiggle it around to check for play. Otherwise you can check the bearing pre-load.

It was a 2 wheel alignment, I understand the rear axle is not adjustable. The truck has never been in an accident and the axle has never been hit. I jacked it up and checked for play in the bearing by pulling on the wheel. I also pulled the breaks and axle shaft out so I could freely spin the hub. The bearing seems to be in excellent condition. No noise, has some preload, and spins freely. I asked the shop about it and they claimed its common on solid rear axle vehicles because the computer has to look around the front tires. I don't really by it, my guess is they just didn't calibrate the machine properly for the rear end.
