If you have abnormal tire wear on one of more tires, it may be due to a bent axle tube, bent spindle or spring hangers welded on incorrectly at the factory. This info. from Lippert shows likely causes of abnormal tire wear: tire wear causes
You can check alignment yourself with a tape measure and long straightedge. Here is some info. on how to do it: checking alignment Check all spring hangers to ensure they are vertical and not to one side or the other at the bottom. Have seen some out of vertical by as much as 5/8" top to bottom.
Here is Lippert info. on how to measure frame & axle alignment: Lip Sheet 0088 Lip Sheet 0143 Ssomewhere there is info. on what the tolerance is for the frame measurements but I couldn't find when I just looked.
This is how they straighten a bent axle on a TT (or FW). It's not something I would want to get done either. New axles are surprisingly inexpensive and not that terribly difficult to install if you have space and tools. Keep in mind that axles have a camber, or "arch" in them so that when the weight of the trailer is on them, they straighten out. You could take a long straightedge and see how straight they are and how the two axle tubes compare.
