12 volt fridges and boondocking?
We have a 07 27' Komfort trailer, I put 480 watts of panels on the roof, we have a 600 watt inverter for the Sat TV and 2 GC batteries. The only time we need to fire up the genny is after 2 or 3 days ...

Doing an audit can be largely guesswork especially if you have not had any experience running that 12v compressor refrigerator. You can start by checking the specs for amperage. A small 4 cuft unit will pull about 3.5 amps. If you camp in cool weather and don't try to cool down room temperature items, you might get by with 30 AH/day. More typical use would be twice that especially when camping in warmer weather. A larger unit is likely to pull well over 100 AH/day.
You also need to be realistic about how much energy you can expect from your solar unit. I am in NY, at this time of year if we ever have a clear day the maximum output for 600 watts of solar would be less than 100 AH. Lots of my camping in done in the woods with little or no solar even on a good day. You did not mention the size of the battery bank but certainly that needs to be sized appropriately also.
