Most RVs I have seen with residential fridges use a 4 battery setup. 2 batteries are the norm for units with a gas fridge. You should not need to upgrade the charger/inverter/converter. It is obviously big enough for the 120 VAC you need and should have no problem charging a couple extra batteries. Remember, when you are dry camping, there are a lot of other electricity draws. Watch TV? Satellite receiver box, furnace fan if it's cold, smoke and CO detectors, water heater control circuit, lights, maybe more stuff. 12 hours on 2 batteries sounds about right.
The only thing running on 120v via the inverter was the fridge. The furnace was on as was the water heater on propane. An alarm went off around 3am and it was an alarm for the inverter for low dc power. I need to learn more about the systems I guess.
