That is exactly how we do it, except when we are at the county fair. There are so many folks there and it is so hot all the ACs are running, you will sometimes get voltage drop. If we want to do something and not have to turn the AC off (did I mention it is hot?), I will kill the water heater for a while just to maintain proper voltage.
