I have a 2017 Entegra Anthem. In the last month, while plugged into a stable 50amp shore line. My interior receptical outlets (inverted) do not work unless the inverter is on. This drains the battery until charged by shore power. Turning off inverter (with or without shore power) the GFCI outlet looses power. This includes the refrigerator outlet. Thus all aligned inverted outlets loose power. Shore power continues to feed all non inverted appliances and outlets.
