If your refrigerator is anything like theirs 60 amps for 18 volt, 12 volts after the charge controller, is about 1086 watts of solar to produce that much charge. You can go with higher voltage panels and a MPPT controller which will help; but your final solar array will still be something like 1200 to 1500 watts when you take in other usage etc.
Based on that you will need to probably mix both solar and ginny run time.
The residential while more efficient then propane is maybe not the best way to go for dry camping. When the cost to run it with a solar/generator is figured in. It is difficult to get rated wattage from solar panels due to real world conditions, dirt, partial shade, or winter sun.

We spend 6 to 8 months a year dry camping.

Where did you end up putting your inverter and other associated equipment. My equipment is arriving today. The panels I've got figured out on where to put them on my 24.1, but the controllers and transfer switch, etc. I'm having some issues with.
