What year were the first trailer houses for sale in Alaska?

Trailer houses were generally first available in Alaska in 1942. The Alaska-Canadian Highway was first completed in 1942 at the time when trailer houses became widely popular across the United States. Before the completion of the highway, the possibility of transporting a trailer house into Alaska was impractical.

Trailer houses serve two functions: mobility and inexpensive housing. Before 1942, mobility was limited but inexpensive housing was common. The Alaska Gold Rush during the 1890s drove the population from 32,000 to 63,000. During the 1940s, Alaska's population rose from 72,500 to 128,500 as a result of the highway. New oil discoveries have encouraged further emigration to the state.
