On average, for that year you would expect to see somewhere between 100k to 120k miles depending on how the truck was used. Double or triple that, I might look twice. As mentioned, earlier version of this truck had fuel pump problems. I add Cetane Boost to the truck in my sig with every fill up and have not had any issues. I have not heard of the radiator, bearing or glow plug problems mentioned earlier so I can't speak to that. If you're serious about this truck, I would definitely look at the service history and make sure there haven't been any problems in the areas of concern.
