Day cab conversion company has roots in Spink County

Farm Forum

As you travel the highways and gravel roads throughout much of the Midwest, you don’t have to go far until you meet a Prairie Technology day cab conversion. It’s distinctive “stretch” cab design or its Peterbilt “fat boy” adaptation clearly identifies the reconfigured truck as the product of the nation’s largest and most innovative day cab conversion company that traces its roots to Spink County in rural South Dakota.

Prairie Technology is the industry leader in the design and manufacture of day cab conversion kits. Many industries, including agriculture, have a need for an efficient and economical means of transportation. Most vocational applications are different than other over the road trucks with sleepers. However, depending upon the truck specs, most of these sleeper trucks can be reconfigured to day cabs using specialized after-market components.

Founder Bill Osman, originally from rural Ashton, S.D., recognized the vocational market needs and set about to develop a method and the components to efficiently and safely day cab Class 8 sleeper trucks. Bill’s original innovation involved a tremendous learning curve since this type of conversion had not been successfully completed by any of the truck manufacturers. Employing a true pioneering spirit, he created a unique design and manufacturing process that laid the foundation for what has made Prairie Technology so successful.

Prairie Technology is a solid, family owned business with “old fashioned” values of honesty, integrity, and fair dealing. Bill remains involved in the design of kits and components as well as maintaining responsibility for the overall direction of the company. Bill’s wife, Wanda, has a master’s degree in elementary education and serves as office manager. Daughters Mary Jo and Elizabeth are taking more responsibility as they continue their higher education studies.

Dave Husby is the general manager for the company. He brings more than 15 years of truck dealership experience as well as years in finance and law. Stan McWilliams serves as shipping and receiving manager with a solid background in inventory and logistics management. Duke Erickson is the R & D manager as well as directing the fiberglass production shop. His experience in auto body and fiberglass has been an invaluable asset. Josh Larson has risen from the ranks to assume overall shop management with a superb background in all aspects of day cabbing and frame work. Tracy Koenekamp manages the metal shop and also lends his considerable expertise to the R & D department.

Prairie Tech is the parent company that supports a wholly owned subsidiary known as Prairie Truck Sales. Tulare native Nathan Ihnen has recently accepted the responsibility as its sales manager. He brings a solid reputation in equipment sales and has had a life-long experience with trucks of all kinds. Normally there are between 30 to 40 trucks of various makes and specs ready for sale.

Bill recognized early on that quality and integrity were essential for the company to succeed. The company has seen dramatic growth through a partnership with a talented group of more than 60 dealerships and body shops throughout the U.S. and Canada. These Certified Partners are trained by Prairie Tech specialists in best practices and procedures in day cab conversions. Close attention is paid to structural integrity, efficiency, and overall fit and finish. Kits are sold directly to the public for non-integral trucks such as Petes, Sterlings, and Western Stars due to the relative simplicity of the conversion effort.

Prairie Technology’s Sioux Falls location has established a reputation for completing extreme conversions. With significant talent in custom paint, airbrushing, frame work, suspensions, fuel tanks, and accessories, the technicians and artisans at Prairie Tech have created dramatic enhancements to new and classic trucks alike. Custom truck work is attracted from all over the nation because of the reputation and excellent work done by Prairie Tech team members.
