The Road King Truck was only released in the set Mountain Mining. The set was based on a diamond mine.The diamonds were the first things lost. The set was only released one year.
The casting was lengthened and modified to create the American Hauler, American Tipper and Movin' On castings, and then lengthened again later to create the original Hiway Hauler.
