Same here. I have about 10k on my unit and noticed abnormal wear on the rear axle tires. I took it to a shop in SLC that I have previously used for trailers; they do alignments on all kinds of rigs. They checked mine and adjusted (bent) the rear axle which was way off. The front axle was ok. Total cost: $68. I rotated the tires (not bad enough to replace) and will keep an eye on it.

This is not just a Montana or Keystone problem. My last trailer (SOB) had an axle replaced, was aligned two or three times and eventually had the springs upgraded to heavier ones.
