Hey Guys, I am about to purchase my first diesel truck in the next week or two and am looking for some tips on what to look for. I have seen a few videos on looking for blow-by, and hazing at starting up thats about it... I want the newer 2007+ body style and worry too much about the CP4 issues so have decided to stick with LMM models around the 100k-120k mile range. Would I be smart to stay away from trucks that were used to pull their whole life and trucks that have already been deleted, leveled/lifted and larger tires? I plan to delete and to have tuned shortly after purchasing. Thanks in advance for any advice!
