Having trouble understanding the water bay heat. When the thermostat engages I hear a pump running in the AquaHot but in the water bay I don't hear a fan. I was once told the water and sewer tanks have heat pads that provide heat to keep the fluids from freezing. If that were true, why would a pump on the main unit run ? Also I watched the amp draw on the 12V and it shows a quarter amp draw with the charger off. So I guess I'm asking if there is a heat register in the water bay like the one in the storage (basement) area. In the past I have found several fans wired backwards so I'm thinking if there is a fan forced register in the water bay it might be backwards as well. (but then wouldn't that force smell into the cabin?) Sorry I ask stupid questions.

You should have two heat registers in the basement
One is for the storage area and the other is just to the side or between the water bay. Two different thermostats and that is why the pump runs to circulate.
That is how my 42GX is outfitted and as far as i know none of the Tuscany coaches had heat pads under the tanks
