I leave my 12v fridge and battery
charger on all summer. Been doing this for years. No problems at all. We normally sail on weekends. It seems foolish to empty your fridge every Sunday night. Defeats the purpose of having a fridge. As to a dead battery and a stinky fridge, jscott, do you turn off and empty your fridge at home every time you go away for a few days? After all there might be a power outage while you're away.
