Welcome to the forum! Here is a link to a post called So you want to buy a trailer three states away
. It lists form members willing to perform amatuer inspections on units close to them. (We all love to kick tires!)
Obviously, get it checked out by a mechanic before purchase. Nothing special about them. P30 chassis with an FI engine (or Spartan with a Cummins engine if a pusher). Check all of the systems, make sure everything works, etc.
Good luck with your purchase. I'm more than a little envious. 360's are pretty good looking rigs.
