I need to turn this thing off to defrost it. There is no name or even a spec label on the inside to identify it, and the useless packet of info that came with the camper doesn't contain any help, for this, or most any other aspect of the camper. Really like the camper, the documentation, not so much. So, with no on/off switch, the only thing I can see to do is disconnect the 120v and 12v power supplies, and the gas supply (although that is probably controlled by the 12v system) to shut the thing down completely. Am I missing something?
