I understand that you have already left your Coach and I am sure it will be fine but whenever I leave my coach for the Winter I don't like to leave it plugged in. I just feel more comfortable with no power to the coach and not having electronics under power unnecessarily for months seems like it will extend their life. Therefore, I remove the main cables from the batteries. When I return 5 months later I first put a charger on each battery individually and every time they all show 94-96% charged when the charger is first put on. I'm not saying one way is better than the other, just what I do and why.
