There is a GMC 3500 nearby me with 14,000 hours on a Duramax/Allison that hasn't needed a whole lot of fixin considering the "easy life" it had in the oilfield prior to becoming a ranch truck. The company did maintenance on schedule...
Local light freight guy ran a Cummins over 1million km in a Dodge. Had to replace a head gasket at 850,000km - liners were still cross hatched...
Towing outfit I'm familiar with ran a GMC gas 3500 500,000km with ignition tune up only, plus normal maintenance, and a zillion $ worth of gasohol...
Common denominator seems to be maintenance :) None of the above trucks are worn out. Still driving around today...
A guy told me Ford will be selling a hundred thousand dollar pickup truck in Canada this year. I thought ya right. So I went on Ford.ca and spec'd a F450 Super Duty all options I could get to stick. It was only C$98,387.00 so he was wrong.
