If you're looking at a truck at a dealer they should have them on hand, write the engine serial # and vin # and perform your own investigation. Also after that a dyno to verify the truck operates properly under a load can give you " some" peace of mind. And yes have some funds on hand to perform what Waterloo stated. This site and its knowledgeable members will provide answers to any questions you might have. Just my 2. Good luck.

Most used truck dealers aren't going to let you do these things. It's much easier for them to just sell the truck to someone a lot less picky. And rest assured they WILL sell it to someone.
