"Look at the entire truck and don't leave anything unchecked. HVAC, all fluid levels and definitely this means the radiator, tires and suspension, electrical system, etc. The air cleaner was completely stopped up and was nonfunctional. Hadn't been changed out in years. There was more wrong with this vehicle when we were looking at it than there was right. I will say though the engine was the best thing about the truck. Diesel engines can go several hundred thousand miles if well maintained, so this one had a lot of life left in it. The interior was okay except for the center console, which was screwed shut at the lid."
