On June 1, 2001 Jim and Jackie bought Mid-States Utility Trailer Sales dealership in Omaha and Des Moines and soon added Sioux City and Sioux Falls to the portfolio. Keizer Trailer Sales added transportation business which moved equipment from Utility Manufacturing plants. Sioux City store was then expanding rapidly and the Keizers leased the adjacent building and plot for trailer parking and trailer service. Keizer Refrigeration already had over 20 employees during the early 2000s, serving mostly customers in the Sioux City and Le Mars areas. In 2006 Jackie Keizer retired from Keizer Refrigeration.
