I know of a 2002 Ford F350, double cab dually with only 131,000 on it. It has the 7.3 diesel and is the Lariat trim level. The guy who has it pulled an air stream for a couple years and was very meticulous in caring for the truck. It is in absolutely excellent shape and was recently serviced by Ford. This guy was into street rods so every vehicle he's owned was spotless. It is located in Florida.
From the Kelley Blue Book, that truck should sell for $13,500 - $17,500 but many are listed much higher.
