Our Schwintek controllers are hot all the time. Not sure about the leveling system (ours is 4 point), but it wouldn't surprise me as both systems are made by LCI.
We do have a rear camera switch in our Eagle (built in October) and not positive, but IIRC it's in the Utility Center near the second water pump switch.
