The 2006 race saw 18 caution flags flown during the race, setting a series record. Dennis Setzer won the 2007 race without making a fuel stop, which took place with a 22-gallon fuel cell. This race took over seven hours to run due to three rain delays and was the final Craftsman Truck Series victory for Spears Motorsports, who ceased operations following the 2007 season.
The 2008 edition was won by Donny Lia, who became the first rookie in nearly five seasons to win a Craftsman Truck Series race. The race was formerly known as the UAW/GM Ohio 250. General Motors operated a plant in Mansfield and a number of its residents used to work there. Appropriately, Chevrolet has won four of the five races, with Bobby Hamilton giving Dodge its only Mansfield victory in 2005. NASCAR announced it will not return to Mansfield for 2009, replacing the race with one to be held at Iowa Speedway.
