Question on UltraHeat tank heater systems
Greetings. I have a 2011 Carri Lite 37' fifth wheel with double walled black/grey tanks heated by a 4" duct from a 40,000 btu LP furnace. I'm outfitting the trailer for 15-25 degree winters in the ...

The heat pads cannot be used on a double wall. As Dave said, the tanks are supposed to be partially full to help absorb the amount of heat that they give off.
I have twin 40g holding tanks and bought the 120VAC pads. They did a great job on my exposed tanks in -20*F (trailer was skirted with OSB). If you were to travel, then the combo AC/DC pads could be a benefit, but heating elements work via electrical current and would have the ability to pull the battery(s) down quickly.
They would be powered separately, you would turn on/plug in the AC plug or flip on the DC switch; they will not automatically switch over.
