I had a 2012 T700, it had 150,000 when i sold it. It was a very good truck i was averaging 6.7-7.0 mpg hauling a 53' dry van, at 35-55,000 lbs. I also rented the prostar, it was not that bad. It got 6.5 mpg. I would overall prefer the Kenworth T700 over a intrnational any day. Good luck to ya hope it helped.
