For 9k, the truck would have to be damn near flawless. I've seen them hit that every now and then, but the norm seems to be more in the 6-8k range. I've currently got one with a blown 460 in it, hit 250k before she died...but that truck did everything I ever asked of it. There were times I'd be loaded up 3-4tons worth of dies in the bed and another 5-7 tons in a trailer and bring them to Hickory Springs or Freightliner, and then return to work with a similar load. If I could do that with a 460, it's scary to think what a 7.3 could do. I've never been in to diesels, but I rarely here any negativity towards the PS. IMO...what you're looking at is the truck to have before having trucks was cool.
