When I and two of my brothers were in grade school, our Dad used to take us to school in our '46 1 ton pickup and also haul the milk in to the creamery at the same time. I was the oldest at about 11 or 12.
If Dad was working in the field, then the job went to Mom. When she drove, the two younger boys had to come along too! Needless to say, there was not a lot of room in that cab with 5 kids and 1 adult! And shifting got pretty crowded too!
