I think having the living area at 70 keeps the under carriage warm. There was no wind on the nights we boondocked so that helped.
The heaters will kill your batteries pretty quickly. I had an AGS that ran the generator a good bit at night to keep the battery charged.

While installing a rear trac bar, I also noticed that one of my tank heaters had come unglued (literally). I called Jayco to get a recommendation on how to fix. They were aware of the glue limitations, and said that basically any new fix would be an improvement. After consulting a friend who knew commercial adhesives, I went with contact cement.
I cleaned the back side of the heat tape (which is attached to a piece of rubber about 1' x 2'), and the underside of the holding tank. Applied a coat of cement on each surface with a small brush. Once both surfaces where tacky, I then VERY CAREFULLY attached the heat tape to the holding tank. With contact cement, you have one shot at lining up the two surfaces. Once it's on, it ain't comin off.
