I'm a pretty big fan of the show (my family watches it often on COZI, and I had Randy Mantooth to do a Cameo recording for my wife for her birthday a few years ago), and I'm 99.9999% sure that this truck is bogus. I believe that one of the originals is at the Los Angeles County Fire Museum. They would probably be the best people to verify whether this truck is the real deal.
