I am looking at buying a '03 f250 super duty in the next couple of days it has about 150,000 miles and seems to be in great shape. I get to go view it tuesday and because its at an auction I cant talk to the previous owner. I know that there is light hail damage which I am not concerned with, however it also says mechanical issues but does not get into detail on what is wrong with it. It has a run and drives guarantee. I am not new to working on pickups, however I have never worked on a diesel. Is there a whole lot of difference in wrenching on them? What should I look out for when I go to look at this truck on Tuesday? Any other tips on what I can do to figure out what is wrong mechanically and if the truck is worth my time and money would be great. I will keep this post updated and I greatly appreciate everybody's time in helping me.
