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 buyer.
Over the years, Sooner has continued to grow its range of products to build thousands of horse and livestock trailers each year. Today, Sooner trailers are manufactured in El Reno, Oklahoma, and are distributed across the United States via approximately 90 dealers located in over 35 states and internationally via its dealerships located in 5 provinces of Canada.
In 2003, Sooner Trailer became the third member of the Universal Trailer (UTC) family of brands, the largest specialty trailer manufacturer in North America. Today, UTC produces a broad selection of cargo, horse, livestock, motor sport, snowmobile, ATV, motorcycle, concession, custom and specialty trailers. Its brands — Haulmark, Exiss, Sooner, Featherlite and Miley — are signposts on the Road to Excellence.
All Sooner trailers feature an industry leading .063 side sheet thickness that adds structural integrity to each model produced.
