So I am thinking about buying a 1999 reg cab 4x4 dual wheel F-350 with 7.3/auto. I have owned a few diesels and even had a similar one to this as a company truck which I liked very much. I know the autos dont last very long even when not abused so I do have a concern about that if it has not been rebuilt in the past. Any other ideas on what I should look for or issues I should be concerned about?
