The radio itself is another, since it uses a bit of current to keep the memory for the station buttons alive. The water heater has an electrical controller that I think consumes a bit of current. The refrigerator also has one. I have a TPMS set that has a signal booster, and - you guessed it - the booster is always on.
Because the phantom loads are small, they may take several days to deplete your battery - but it will happen. It is not really practical to identify every phantom load, and add a switch to turn each one off. Instead, if you plan to store your camper for more than a few days, you should either disconnect the battery, or add a "battery maintainer" - basically a very small battery charger. Neither is very complicated. By using the Search function on this Forum, you can uncover a lot of information about both.

When we are storing it in our garage, would there be any harm in leaving it plugged into the house all the time?
