Our Chevy 3500 ('03 Duramax) wrecker made it over 300,000 miles but by the end probably barely made 150 HP, and through its lifetime had a lot of fuel system, electrical, and rear-end problems. The transmission never hiccuped once however.
Our '05 Chevy 5500 fared much worse, as it was often loaded to about 28,000 combined. By 200,000 miles it had to be traded off. The engine actually wasn't in terrible shape, but the extra heat from working hard effectively cooked all the wiring harnesses under the hood, so we were constantly chasing numerous faults that would make the truck stall or go into limp mode. It actually became a rolling road hazard, which is why we traded it off earlier than scheduled.
