Unhook the NEGATIVE side of battery and put a test light between the batt and cable on the negative side if it lights up you have a draw on the system. On the motor home they make trickle chargers to hook up why you are not using it. On the first if you do find a draw usually it is a bad overhead light. if not unplug fuses till it goes out and then you know what system is drawing the battery down.
