Deep cycle batteries most commonly used on an RV would be either Group 24 each 20 HR rated at about 75 AH apiece, half of which is usable when discharged to 50%, or Group 27 each 20 HR rated at about 90 AH apiece, half of which is usable when discharged to 50%.

Nonetheless, you too want to make sure any climate control heating element your fridge may have is disabled whenever you are running on battery power.
