G' day Willie, to me a Truck is a Truck is a Truck. It can be a Roadster Truck, a Pie Truck, Bread Truck, Milk Truck or whatever. So many variations were made/built back in those days and used as a truck, it was the times and that is one thing that I like so much about that era. Good ole American ingenuity. My grandfather made a Truck from a touring car and pedaled goods from Tennessee to Texas.
