My truck is a 97 f super duty with 385k on it flatbed hay spike winch single cab and the last time I blue booked mine I believe it was right around 8 to 9000 and it leaks a tad bit of oil but if you could get the truck for a low price and fix it up it would be worth it.
I am glad i have found people that are into diesel like I am it has ran in my blood since i was a little kid there are a bunch of wanna bes in my part of the country like for say stacks on a gasser really but the guy thinks his truck is just as good as a diesel but his truck would fit on the bed...
