I think I would be tempted to find and repair the real problem. Why is your voltage going so low?
I asked that same question and I was told that's not unusual for a rig my size when dry camping in the mountains. Highs can be in the 70s with lows in the 20s. My furnace turns on frequently in the evening along with the normal electrical things like the fans for my fridge. I've had my batteries tested by two separate organizations and they are good. If I top off the batteries several hours before I go to bed, everything is ok all night. Realistically, you're up doing things with lights on until you go to bed. I also have solar panels that top off the batteries during the day but the time between sunset and bed time knocks the edge off the batteries and down to about 12 volts. When I monitor the current draw during the day, I don't find any one thing that causes me concerns.
