Sooner Trailers - Premium Custom Trailers - Sooner Trailer was founded in 1956 by Francis Cobb. The company didn't actually build trailers then, but the idea for constructing top quality devices for transporting animals began when someone needed a stock rack and Cobb agreed to build it for them.

From these humble beginnings, Sooner Trailer grew under the ownership of the Bernhardt family of Duncan, Oklahoma to build premium quality custom aluminum trailers to meet the needs of the most discriminating and experienced buyer. Over the years, Sooner has continued to grow its range of products to build more than 2000 horse and livestock trailers each year. Sooner trailers are distributed across the United States via approximately 80 dealers located in 37 states and internationally via its dealerships located in 5 provinces of Canada.
