Utility Trailer Manufacturing is spreading its own brand of reefer madness. Utility Trailer is one of the US's largest manufacturers of refrigerated trailers, or reefers, as they are known in the business. The company also produces dry freight trailers, flatbeds, and curtain-sided trailers at five plants in the US. Its refrigerated trucks include special designs for the whole food distribution and fast-food markets, such as a truck with separate chambers for frozen and dry goods. The company's trailers are distributed throughout Canada, Mexico, the US, and to a lesser extent in Argentina. Two brothers, H.C. and E.W. Bennett, founded the company in 1914 and their descendants still own it.
