I can say that I've now personally had similar experiences. We have 2-100ah Lithium batteries and the lowest I've ever had them when off grid was 40% after watching a couple of hours of TV, running lights, making a pot of coffee and the fridge running for 14-16 hours with limited solar charging. If you are only concerned about travelling down the road and start with a full charge every morning on your Lead Acid batteries you should be good to go.
Thank you for the encouragement. I am feeling better about traveling with the refrigerator running. As @Daryles recommended, we will try the frozen water jugs. I will also wait to put any frozen meat in the freezer until I'm hooked to shore power or am confident that my 12v will have enough charge to keep everything cold. Incidentally, I am not going to use the ice maker. I disconnected the water line to it after my winterizing. I may remove it altogether for the extra space. I will also cap the water filter receptacle in frig as there will be no water hook up.
