I agree with everything everyone here has posted and one has touched on electrical management. Coming into cooler weather you may not be running the air conditioner but the times when you do you may want to shut off the water heater. Its not going to be life or death to your AC but conservation is always in order IMO. I turn my WH on and off as needed, like in the morning for showers and evening for showers. My tank stays hot enough through out the day to wash hands or dishes or anything else that I may need hot water for. Why waste the electricity..... even if it is "free". Some older parks with older electric systems may need you to conserve so there is adequate power for all the park.
