“The Heavy-Duty Truck Capital of the World” was the nickname for Truck Plant 1 at the Fort Wayne International Harvester Plant, now the plant is going to be home to the Harvester Homecoming Museum .

"Whether it was war vehicles, work vehicles, school busses, they didn't just build trucks here," Duvall said. "They changed transportation in the United States. This was built a few years after the Lincoln Highway opened, the first transcontinental highway, and they built a heavy duty truck plant right off of it like a stone's throw. And so basically, long haul trucking was perfected right here."
