In this video I give a full in depth tour of a Custom 2005 GMC Sierra 2500HD Durmax Diesel. I take viewers on a close look through the interior and exterior of this truck while showing details, over viewing of features, and noting unique styling cues to the vehicle itself. I also show the engine and the details of it, start it up and see how it sounds. A thorough tour/review of this truck designed to give others a greater overall appreciation of the vehicle.
