Diesel pusher chassis supplier Spartan Motors Inc. has appointed auto and heavy truck industry veteran David R. Wilson, 65, to be its new chairman effective next June.

Wilson, an outside director of Spartan since 1996, will replace Spartan founder George Sztykiel, 71, who announced earlier that he planned to retire.

Sztykiel also will give up his role as CEO effective next June. Wilson is chairman of the special Spartan Board committee conducting the search for a new CEO.

Wilson currently is an independent consultant to the auto and commercial vehicle industries specializing in marketing, product development and strategic planning.

Prior to founding his consultancy, Wilson was vice president of Volvo GM Heavy Duty Truck Corp., general manager of field operations for the commercial vehicle division of Mercedes Benz of North America and he spent more than 20 years with the Chrysler Corp. truck group.

“His (Wilson’s) leadership and industry experience will be important assets as we emerge from the turnaround that’s been taking place over the past year and begin implementing focused growth initiatives in our core markets,” Sztykiel said.

Spartan also announced that two other outside directors, auto industry analyst Kim Korth and investment banker James Penman, resigned from the Spartan Board. Korth joined the Spartan Board last January and Penman joined in 1997.

In addition to building chassis for motorhomes, Spartan also assembles fire truck, ambulance and specialty vehicle chassis.
