Semi tractor-trailer trucks have been a fixture on American highways since the 1950s and today's rigs are nothing short of homes, offices and money making machines on wheels, utilizing the latest in technology. The days of two-man cabs have been replaced by luxurious cabs with sleepers that include a bathroom and kitchen, and the citizen band (CB) radio has been replaced by the cell phone, global positioning system (GPS) and satellite television. There are hundreds of commercial trucks, trailers and other heavy duty equipment listed for sale on every year and these are some of our favorites.
