As for body parts check all the door hinges. If any of them have paint chipped off of the head of the bolt thats an indication that there has been some body work. Same goes for the front fenders and hood. If the truck is already warmed up when you get there that raises a red flag. Look for oil marks on the ground were the truck is parked.

While this is true in California and some southern states. Not necessarily true in states that get snow and ice. (Road salt is hell on paint)

What I'm saying is if the door got smashed and a new skin was put the door would have to be removed to repair it and it would leave marks like this indicating some kind of repair has been done. You can see socket marks on the bolt and nut.
