Richard and Lowene Gray purchased and began operation of the family-owned business, Spencer Truck Line, in 1971. At that time, it was strictly a livestock transportation business with three trucks and three trailers. Years later they purchased a straight truck to move smaller loads. All of the customers for the business at that time were local farmers. The drivers were Richard and his two sons, Rick and Terry. His wife Lowene worked in the office answering the telephone and handling the books.

In 1988, Terry Gray took over the family business, along with a new partner, Rick Adams. The business stayed true to its livestock roots until 1992, when it decided to expand into van freight. They began hauling furniture for Stylecraft, a branch of Klaussner furniture, nationwide. Spencer Truck Line, Inc. still moves loads for Stylecraft on a daily basis.

Spencer Truck Line, Inc. now owns 14 trucks with 4 owner operators, 32 van freight trailers, 9 livestock trailers, and employs 35 full-time and part-time employees.
