Hi SunTen,
I'm in a Class C RV.
I've added electrically operated heaters to the waste tank and water pump areas. They are controlled by mechanical thermostats to prevent freezing.
The dealer is correct--it is possible to use too much electric heat, unless alternatives such as the above are carefully used.
Do read the first part of the thread--lots of good information there.

I appreciate the information. How do you use heaters and keep heat going under the 5th wheel to keep things from freezing? My dealer said I should always have the furnace working because it puts heat through the floor area of the 5th wheel where the furnace vents are.
