I am posting this as a point of reference for others who may use similar setups.
I just got back from a 4 day trip to Arizona/Utah border. Total of 600 mi round trip. We camped for 3 days/nights using only solar/35ah battery that ran the fridge and lights and cell phone chargers.
The PV module was not ideally positioned as it is fixed flat on the Willys roof, but received most of the days sun. The weather was mostly clear with some high clouds.
The frozen food stayed frozen and canned drinks were removed and added as needed.
The battery never dropped below 50% and recharged completely each day.
My take away is that the 100w module is the key to indefinite operation of this setup. Think a larger battery/smaller pv module would eventually run low and disconnect.
My decision to go with a smaller battery and larger module seems have been correct.
