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 ...

12v refrigerators will likely use 30-60AH/day.
Your propane refrigerator does use some 12v power, but let's assume it is small enough compared to the amount the 12v refrigerator uses and you can ignore it.
Your two 100AH lithium batteries gives you probably 20-30 extra useable AHs compared to your two 6V batteries.
The 600w of solar gives you 120w more than you have now. In a sunny environment that will give you 25-35AH/day more than you had.
From the above, it seems like it is about a wash and if you were okay before with your battery life/use you will probably be ok with this new rig.
If the new rig has a generator, then you've always got that as a backup. My suggestion would be to try it out and see if you are satisfied. If needed, you can always add one more 100AH lithium down the road and another solar panel or two.
Good luck!
