I have successfully RV camped without using propane for several years using only electric hookups or small inverter generator.  I do most hot meals and heating of things using microwave.  Occasionally I use outside a one burner propane stove for cooking or heating soup, etc.  Again use the microwave for heating water for washing and cleaning  and occasionally check into motel for thorough hot showers and good scrubbing.  In hot weather use the outside RV shower hose wearing swim trunks or use the indoor shower.  Use a small electric fan heater in winter time inside Rv.  Have a small but powerful electric floor fan  for outside the RV in hot weather. In addition to electric fridge I use ice chest sometimes. To each their own. Always a way and all is good
If I want home cooked meals I go to restaurant or stay in the city.
Camping and fishing is what is important to me and not full timing.
