OP here.
My primary objective is to finish a daily battery charge with the generators and the 100 amp converter in the shortest time practical. When boondocking, the residential refrigerator will use about 150AH (estimate) daily of battery capacity.
So I want to choose cables that will help with that daily charge and help the 200 watt (or 400 watt) solar panel(s) get the most AH into the batteries as is practical.
I believe your initial assumptions are a bit skewed and why wouldn't they be since your power use hasn't been documented or probably even been researched by the mfg of your RV, An owner is left to find out on his own and adjust electrical matters on his own.
I use a small 120 V dorm fridge and my research shows that power consumption is not that different from a full sized box. The larger fridge will consume more power because of a larger freezer compartment but is better insulated. I average 40AH-60AH/day. Your larger fridge may consume 100AH/day but that would be the maximum.
With 400W of solar charging available and fairly good insolation conditions, your batteries should be fully charged by the afternoon. The use of a generator may not be necessary. Your power consumption will also be defined by the other devices you use like alarms, entertainment gear, battery chargers for phones and computers, the draw of the fridge, water heater, and furnace, and others. I would be surprised if you need the generator during good, sunny conditions. There are those rainy/cloudy days or parking in a tree canopy that makes an available generator a "must have".
Good luck with your new rig!
