Bob:
Many things are using current, even if they are "off".
First, though, does your coach switch work? On my coach, turning the switch off disconnects the battery completely. My switches malfunctioned, and had to be replaced.
That said, your electronics draw power even though they are off. From your TV, to the stereo, radio, anything plugged into the cigarette sockets, refrigerator, clocks and monitors (including carbon monoxide and propane).
Purchase a "Kill a Watt" and test each circuit. You will be surprised on what is drawing power, even though they are in their off position.
What type of battery is supplying your 12v power to your coach?
