Mileage is only part of the story. Hours in combination with mileage will tell you more.
VERY TRUE
When I was looking at 06 and 07 Duramax equipped trucks, I saw one that looked tempting. It had about 66,000 miles on it, but the hours were up over 6000 hours. That meant it had sat idling a LOT. I found out it came from Alaska and was a "fleet" truck.
When I go truck shopping for used trucks, I always look at the hours too. I know GM trucks from 99 and newer show engine hours, but I don't know if Ford / Dodge (RAM) trucks do.
