How is this for a power system? Solar vs battery balance?

Thanks everyone for the great thoughts..... Matt at Hallmark suggested that with that big fridge.... 380 watts solar (two 190 x Grape panels) plus a 200 amp hour lithium.

I think we will also carry a generator just as backup.... in the optional cargo storage bins off the back of the Hallmark. The Honda 2200 fits perfectly, they say.
