Sooner or later, everything wears out. You could get half a million or more miles out of some diesels, but only 200,000 from others.
I guess by not being totaled out, scrapped for parts, or rebuilt/replaced, you could say it has a good track record, but it's getting near time for some accessory component to fail, and it could be $50 fix up to $4000 or more. Bottom line is no one can answer your question. It could blow a set of injectors at 160,001 miles, or be trouble-free for another 100,000.
That being said, if the price is right, the price is right. Personally, I would have to know every detail of the truck's life, or it would not replace my daily driver until I put some mileage on it personally.
My brother had a '93 Chevy 1500 Z71 with over 280,000 miles on it. He is a mechanic, who also drag races on his own time...forever working on cars. He knows more about cars than I ever will. When he traded it in on his '05 F450, the Chevy was still running strong. This is an example of what can be accomplished if a person knows how to maintain a vehicle properly.
When I bought my '05, it had 43,000 miles on it. I will bet my house that the original owner NEVER changed the fuel filter. It was practically dissolved when I pulled it out. My head gasket went at 60,000-something miles, and I suspect the orig. owner's lack of care had a lot to do with it.
