Tim, I'm kind of like you about AquaHot. I have ordered 3 new Dynasties, and one HR Scepter; all without AH. I don't spend any time in cold weather, so am not interested in engine preheat. We are almost always are in a full hookup campground, so we have power to heat water. I agree that the furnaces are noisy, but in the environment we are normally in, we just use space heaters with thermostats built in. We let them run all night if necessary. I know that there is a lot of support for AH, but it has not been of interest to me.
