The main body frame is completely rusting through from under the drivers side door back past the fuel tank. It is rusting through on the passenger side as well. The large amounts of rust have caused other issues throughout the entire body of the truck as well as rusting of other components. The frame of this truck will need to be replaced as there is no way to repair it or the vehicle becomes scrap. This vehicle is available for inspection. These issues were not visible when purchased from the dealer. This issue gradually became visible after the rust and undercoating wore away that had been applied previous to our purchase from a known dealership.
