I'm going to be in the market for a f250 or f350 in the near future and had a couple of questions. I've never owned a diesel before so please look over my ignorance. I have been looking at the 6.0 trucks is their any certain years that seem to have more problems than others. What should I look for in a used truck to tell if its had a rough life { thing other than the obvious } I'm looking for a crewcab that will basically be used for lite winter use and to pull a 16ft trailer in the summer for my lawn care service. Any tips or suggestions will be appreciated.
