The only thing I can think of, and my memory is fuzzy on the subject, but in the early years, 99 and a few years beyond, there was a problem with the frames, and Lippert had a recall and an expansion joint installation resolved the issue, so if you are looking at one of those years (dealer or Lippert should be able to tell you specific years), make sure if there was an issue, the expansion joint was installed. Only Montana specific issue I can think of to be aware of. As indicated above, competent PDI is the key.
