i ran a car-fax on it and the second owner had it for 178000 miles then owner #3 and #4 which is the guy i am possibly getting it from both owned it for less than 6 months. That just seemed weird to me and in some cases in these deisel trucks points to a problem or something big like injectors are going bad. The guy was supposed to be bringing it to me from 3 hours away but cancelled because he got busy for weekend. I have a mac scanner and told him i was going to be putting it on it to check it out before i would say yes shortly after that was said he cancelled for the weekend. He has given me everything i have asked for up till now. I really want to do the deal because I plan on taking my injectors to 100% and it takes approx. two weeks to do and i would not have a truck for those two weeks plus I want to put the cap on my dually, I think it would look cool on my truck. thanks for all opinions. Just had heard some bad things about injectors in these motors!
