In America these massive, weighty breakdown trucks with their typical lifting cranes that see service round the clock are called "Wreckers". Also known as "Tow Trucks" they use chassis from well-known manufacturers like Peterbilt, Ford, Mack or Kenworth. These firms primarily make cab-behind-engine trucks. These "conventional" enjoy great popularity, not only with the truckers, but also with salvage and towing firms. The typical crane superstructures, inclusive of technical equipment, are supplied by special firms such as the famous Miller Industries in Ooltewah, Tennessee, who fit out the trucks with the required superstructures and supply them under individual names such as Champion, Eagle or Challenger. The same applies to the wrecker called the "Century" from Fred Viohl, owner of a motor works in Haverstraw, New York State. Viohl had a Miller type 1040 B superstructure mounted on his W900. The three-stage crane jib has a maximum lifting capacity of 40 tonnes, supported by two powerful Ramsey winches. The 6-wheeled W900 is driven by a 400 bhp turbocharged diesel engine which, as shown on the model, is located under a bonnet that lifts up forwards. The large towing trucks are conspicuous, not only for their imposing external dimensions, but also for their fantastic paintwork. Like the original, on the model the rearstabilizers can be lowered, the crane jib extended and the winches rotated.
