Marcus Richmond will take over the duties of crew chief on Cole Custer’s Number-00 Junior Motorsports Chevrolet for the remainder of the 2016 Camping World Truck Series, beginning with Saturday night’s race at Iowa Speedway. He replaces Joe Shear Junior, who resigned earlier this month. Richmond has 205 starts as a crew chief in the Truck Series with nine victories. He helped steer Ty Dillon to a runner-up finish in the 2013 championship standings, behind only Matt Crafton. Richmond has most recently served as a crew chief at G-M-S Racing. Custer is currently fourteenth in the standings after seven races, twenty-three points shy of a Chase berth with nine races remaining in the regular season. His best finish this year is fifth place last month at Dover International Speedway.
