I have been looking at Diesels for awhile and am about to make the jump to the dark side. What are some of they things to look for. I am looking at an 08 F350 with 74,xxx miles on it. It is on Warrenton Selects website in Virginia. Any help would be greatly appreciated.

I don't know too much about Diesels but know what in mods. This truck has a few of them.
