House Lifeline Battery Question (again)
It sounds like the battery can't hold the charge as long as it used to or isn't getting enough charge during the day to reach full capacity.
Try plugging in your van for 12+ hours to get a good/full charge, then run the fridge overnight (or your normal overnight draw) and see where the voltage is in the AM.
