I'm storing 1 1993 Pace Arrow 35V beside my garage, with a cover. Up to this year, I have left it plugged in to shore power and checked everything once a month. My vehicle battery has always run down (even starting it up every 6 weeks or so). Interstate service people discovered the vehicle battery is not charged by the converter. So this year, I have used the battery cut-off switch, so nothing is draining the power. They advised that as long as the fluid level reads in the green, don't need to worry. But I do. How often should I check the batteries (usual storage time is 3 months) and should I still start it up every so often? It's a nuisance to pull off part of the cover (especially when snow flies). Any suggestions? Thanks!
