When we were on the walk through of our new rig the guy said never have the electric switch on when using propane to heat water. He said using them both at the same time would overheat the hot water tank.
Does not make sense to me. Seems if you are at an RV park using electric power one would not use propane. And of course dry camping one does not have 110 so propane is it.
In past rigs we never gave it any thought and did not have a problem. Am I missing something?
