For reference, my 97 Powerstroke has 250K miles, and other than oil changes every 5K miles, I only maintain what breaks. Coming from this frame of reference, a fleet vehicle with only around 100K miles didn't bother me at all.
EM gives you a 12 month or 12K mile powertrain warranty, so anything immediately wrong, i.e., something that a private seller might be trying to pass off, gave me even more confidence. I put 6K miles on mine in the last month w/o a hiccup.
I had dually simulators put on at a local tire place (Les Schwab)and they checked the brakes for me; and they were brand new. With a rental business model, I figure they need to make sure there stuff doesn't leave anyone stranded in the middle of a vacation so they make sure the coaches are safe and within what can be predicted, reliable.
