Last year was the first full winter that I owned our coach. We store it inside a large building with other RV's. The building is well sealed but is not climate controlled. Our winters can get very cold (come on global warming) and the coach will be in storage from about the first week in November until late April. Last year when they started her she churned for a while and finally started. We have it winterized which includes checking battery water level and adding something to the diesel fuel that preserves it. Should I do anything else? I see these battery tenders advertised in camping world. I am not sure there are reachable outlets in this building but I worry it won't start in the spring and if it is bad for the batteries to sit like that.
