BTW this is what the van (his first car in 1978) looked like - except it wasn't as immaculate, had some rust, and he had all sorts of stickers on the back like was common in that era).
Compared to a USA truck it is tiny.
Dad did install a fairly decent Japanese radio cassette player to listen to his Country and Western with (you had to do that yourself, vehicles didn't come with their own built in radio back then!)
