Did anyone look at the pictures of the inside of this thing? All the equipment that would make this interesting has been stripped, but also, all of the beds and furniture that make it useful as a camper are gone. If someone buys it at this overinflated price they will have to make a decision whether they want to try to restore it, or remove the equipment cabinetry. You can't do both, they're mutually exclusive.
Most of the museum value of this thing would be to park it outside and maintain the paint job, it's not some great untouched historical relic. I have the distinct impression that this news coverage has just been the seller attempting to drum up any interest on his auction flip.
