Electric Tank Blankets
I've previously asked a question about "Winterizing" an RV - and have recently received emails from Camping World advertising electric water tank blankets http://www.campingworld.com/shopping/item/...

I recommend using either the 12V heating pads or the combination 12V/120V heating pads ... instead of the 120V only heating pads. This will provide the flexibility to protect your tanks in even the rare situations where you might be dry camping in cold weather.
I see nothing on the UltraHeat website saying that their 12 volt DC heating pads were less effective than their 120 volt AC heating pads when running off 12 volts DC. Probably their heating pads are designed such that their amperage draw is higher in the 12 volt DC mode so as to supply the same heating BTU energy as when their heating pads are powered from 120 volts AC.
We have 12 volt UltraHeat pads on our tanks since our RV always has 12 volts DC available, whether drycamping or on hookups.
