the 1964 Ford Econ-O-Line known as the Collins Van by ham radio operators, as it was the mobile show room that toured the country for 2 years advertising the radios,

effectively too, as a lot of guys picked up the hobby, and used it during the Vietnam war to communicate for free, to the people back home
