Is your fridge electric only? What amps does it draw on electric, or are you asking about using a propane fridge that needs a little bit of DC electricity to run the circuit board?
Those 1-2 times you are without shoreline then just run fridge on propane. You really never want to run an absorbtion fridge on batteries, that is extreme and will shorten batt life more than anything.
If it is an electric Danfoss compressor fridge then no worries.
I have the Ryobi 2200. It is a champ. Yes, I can run 10-11 hours on that one gallon tank running just my roof ac (9200 btu). I do not charge usually when using AC as that one gallon will get me through the night, and I have solar. however, I can have the batt converter on and run the AC, but this will use more gas, so I will only charge just as much as I need to get me through the dark hours.
100 watts will keep the batts topped off. To charge them from a depleted state will take longer. I highly suggest 200 watts minimum if you live in the southern part of the country, perhaps more if northern.
MPPT charge controller and you are good to go. Lots of info on installs on this site.
The 100 watts of solar is perfect for storing the RV. You will not have to worry about plugging it in or to wonder if they are getting maintained. The charge controller is always monitoring the batts and providing what they need.
