I say this based on experience. There are several parasitic loads on typical house batteries. 100 watts is probably overkill on bright sunny days, but on cloudy days it may only provide a fraction of the potential power needed to maintain the batteries. Our old coach had a 10 watt panel on the roof attached to the house batteries and it didn't even come close to keeping up even on sunny days. So it does seem like a lot, but it is planning for the worst case.
We currently have 400 watts of solar on our roof and are looking at adding to that since our power budget has gone up. Of course, we also have 4 group 31 AGM batteries for the house as well and they take a lot more power to charge them fully. So we end up running the genny more than we would like.
