How long will new batteries will keep charge when disconnected
I am getting my 2017 Berkshire XL 40 in a couple weeks and since we live in an area that does not allow RVS to be parked on driveway, I made arrangements to store it a few miles away in an outdoor storage facility...(indoors would have been great but at $700 a month I could not justify it).
I understand the RV comes with a battery shut off switch, so nothing should drain them at storage but since I don't have shore power how do I charge them? How long will their retain their charge? Will the engine charge the 4 deep cycle 6 volt house batteries or most likely will I need to run the generator while underway?
