Each coach is different with regard to drain on engine battery. If you can go a month you are in great shape. Some may need to go 3 or 4 months and not use or not start generator if not longer. I have never had to use my engine disconnect switch because my RV is stored at my home, but I have switch that I can turn off anytime I need (if I need). I may be able to go two months? I will never know because I don't have to try.
