Should I keep the 5er plugged in for the couple months of storage, or remove the battery and put it on trickle charge? I noticed while plugged in the converter is powered and running and also the transfer switch is energized and humming. Is this unneccessary running harmful to either of these? Does the battery have to be installed to run the 12 volt items such as slide out, landing gear, etc, or will the converter run them? I am leaning toward leaving it plugged in, because I will need the battery to start and excercise the generator.
