Six-cylinder diesel engines await installation in trucks assembled at Hino Motors in Williamstown, the state's first vehicle assembly plant. Customers equip Hino's commercial trucks for a variety of uses, from hauling beverages to hauling waste. Brink's turns some Hino trucks into armored vehicles.

Hino Motors' Eric Welch of Belpre, Ohio, installs a rear-view mirror on a partially assembled truck cab. Nearly half of the components in the trucks assembled at Williamstown come from North American manufacturers, said Justin Wager, production manager. He said Hino wants more of the trucks' contents sourced locally.
