The loading has not changed and my side to side weights are within 200 lbs of each other and are opposite to each axle. I run 5 psi over what the load tables call for as I'll still travel with a really strong cross wind... in fact this past week I had 93 degrees on one side and 118 on the other because of a good cross wind.
The only easy measurement while on the road for the rear axle is it's relation to the tag tires which are identical on each side. DW helped me check the toe in... less than 1/8th inch and it's not a wandering issue.
