My father ran a dairy for 30 years. We had several dozen Divco, Flxible, and GM delivery trucks. When they decided to stop retail home delivery, the trucks just sat in the lot and rotted away. Who knew they'd have value someday? After all, something most folks don't know, is that most home delivery trucks were not refrigerated so they had to be heavily insulated to keep the product cold. That meant your average 1950s Divco weighed in at well over four tons so moving a nonrunner took a heavy duty tow truck. No wonder no one wanted one of them...
One bit of trivia about the Divco model U was that it could be driven while standing up. As a kid, I always thought that was so cool!
