This load of three new 1930 Model “A” Fords is on a semi-trailer manufactured by the Taylor Truck-a-Way Co. of Los Angeles, CA. At the time, a rig of this type was used for local and regional transport, and long-distance transport of automobiles was handled primarily by train. The lightweight trailer frame is constructed in the form of a lattice truss that is resistant to bending. The lower part of the fifth wheel hitch on the truck is of the conventional type but uses a lightweight horizontal top section, as seen in the second photo below.
