In 1942 the Palace Corporation came out with a revolutionary new type of trailer (Palace Expando), one that expanded out on both sides. The model featured four rooms and a shower bath. The US Army purchased thousands of these models as base housing for the enlisted men and their families. This trailer was designed by William Bushnell Stout who also built the first all metal airplane in the United States and started the first regularly scheduled airline in the United States.
