Mine is getting ready to turn 140k, I have only had it 2 years, I am the 2nd owner, I have probably only put about 7-8k miles on it, the previous owner, was a lumber salesman, I bought it from a small rural chevy dealership, everyone knew the guy who had owned it, he has been a regular customer of the dealership for many years, in fact one of the other salesmen said “Hey, I see you’re buying my neighbors truck.” lol. They had performed all the service and had all the service records. Records state it has had a new throttle body at some point, probably from oil build up, but other than that, nothing but regular maintenance, thing runs like a top.
