Thanks to a friend who alerted me to their
presence on Facebook the other day, I already messaged the owner and suggested reaching out to the Michigan Flight Museum and Military Aviation Museum (the latter because of their
recent interest in ground vehicles) about the trucks. Even if the former didn't want to acquire them, they could still place them on display on loan while the owner attempts to find a buyer. It would be a good win-win as it would allow the owner to advertise them as well as allowing the museum to show them off for some period of time.
