If I were gonna do a whole theme camp about baking, I'd round up one or more real, home type gas ovens and bring 'em. They can be had cheap used and really don't weigh that much. That'd really be the shit!
Since it wasn't mentioned, make sure to investigate all the legal hoops about public food service.
