Added a 1966 B-75 Mack recently to my fleet and am wanting to haul my other B-61 to shows. State of VA says if I hook a trailer to it that I am considered a commercial vehicle and am no different than new truck. I had planned on tagging it antique, but DOT says otherwise. Does anyone have any suggestions or ways around this. It would cost around 1000 bucks to tag it commercial in VA. That seems like a whole lot just to take it to shows a couple of times a year. Thanks Robert Abingdon, VA

Just bought a 1966 B-75 Mack with quadraplex trany and END 711 motor. I already own a B-61. Does anyone know how many of the B-75's were made? It is a neat truck. What is the main difference in the 75 and 61? Thanks for the info. Robert
