I understand what everyone is trying to say but somehow my main question was missed. What I asked was whether we could install a solar panel and regulator dedicated only to the frig and would that keep the frig cooled properly.
Yes you can.
I would suggest that you look at whether this would be a waste, in that configuration. By that I mean that it may be more efficient for you to increase the number/size of your current coach batteries. I think of it as having one large source, instead of two smaller sources.
Key note is, as asked above, How much solar, and what do you do on a rainy day?
