Look over the paint and body extremely carefully BEFORE leaving the dealer lot. Techs doing pre-delivery inspections, recon guys cleaning the truck, and lot gremlins can leave small dents and tiny scratches on your truck. These things just happen sometimes, but it is a dealer's responsibility to deliver a new vehicle in new condition to the customer. If you can prove these things were wrong with the truck at the time you took delivery, the dealership has to fix it. Basically, I like to find out what's wrong with the truck before I get it home and can't prove who did it.
