Kenworth Sales Company was founded in 1945 by the Treadway Family as an intermountain Kenworth Truck dealership. The partnership was organized to carry on general sales, parts and service of trucks used in intra-state and inter-state hauling, construction, and farming under a dealership agreement with the Seattle, Washington based Kenworth Truck Company. With a small staff of family members the Salt Lake City based business incorporated in 1950, and prospered under the friendly work ethic of the Company founders. Expansion came slowly at first, and accelerated in recent years:

We are in business to serve the customer with the best line of heavy and medium duty trucks, the most complete inventory of parts, and the highest quality of service available.
