My Volt meter reads 12.5 with a full charge in the battery, If I turn on only one light it will drop to 12.4 When I ran the fridge all night the next morning the meter reads 12.2 volts, with the generator running or when plugged into shore power the meter reads 13.6 volts, I ran the fridge all night and the battery was still just about a full charge, It took very little to run this fridge all night.
If I understand what you are saying that the voltage was 12.2v in the morning, then the battery is half discharged (not "just about full charge") and you are not supposed to discharge a battery more than this. So, you are only getting less than 24hrs of run time (fridge plus whatever else you were using) before the battery needs to be recharged. I don't know what the charge capability your system has, but my 35amp smart charger takes 4-6 hours to recharge a battery from half discharged.
