We have the same FWC Fleet with the same solar system, batteries and refrigerator set up and are happy with its performance. It does what we expected it to do.
Expectations are everything. I have 250AH of battery, and 265W of solar on the roof (plus 200w portable). At the moment, I would be glad to get 50W out of the roof panels for 4 hours, given the angle of the sun (I'm in Calgary) and the slight dusting of snow on the roof today, even in super bright sunshine. That's 16AH or so. I would not expect my rooftop solar to keep up with demand from my furnace/lights, even at a low 5A max total draw at most times. 5 hours at 5A = 25AH, which is what I also see on my Victron BMV.
The OP's batteries and solar array are way smaller, and have rain/cloud to contend with. My system would not cope well in those conditions for more than 4 days, tops. And installed myself, it was still $3000 USD in parts.
