Wilson Trailer Company

Wilson Trailer Company is an Iowa corporation, independent (privately held) cargo trailer manufacturer headquartered in Sioux City. Wilson manufactures (i) industrial road transport trailers for livestock, grain, and the like – flatbed and gooseneck design, aluminum and custom – and (ii) trailer-equipment and accessories such as self-unloading belt conveyors.

History
Frank Taplin Wilson founded the company in 1883 as a small wagon and carriage shop in the Huron territory, South Dakota. In 1890, he moved to Sioux City, Iowa, to join his brother, George Washington Wilson (1859–1913). Wilson Trailer is still family operated by the fourth and fifth generations.

Big band history – sleeper buses
In the late 1930s, Wilson began manufacturing sleeper buses for big bands, notably territory bands. Lawrence Welk has speculated that he was the first to design and use a sleeper bus.
