I am using 120 volt heating pads from Walmart. My tanks are enclosed and I do have a good sized inverter...
Unfortunately where I live -40 is quite possible.
That is amazing--24 or 40 below in an RV! So you have two 50 watt heaters on each tank? I know 120 is better at heating that 12v but I wanted to be able to use the least amount of power and still have some freeze protection. I had more batteries at one time, but killed all four and now only have one Walmart DC.
Don't know how much winter camping we will do. But I wanted to try it. During our warm up last week though, I drained and winterized the plumbing. Didn't want to run electric heaters in there all winter. It may be awhile until I get the tanks insulated. I'm planning to build polyiso boxes for them.
