I've been looking into ideas like this for a little while. Its 1000W so would need a large (expensive) inverter to use that. I hadn't considered carrying the jug to a building and plugging it in outside though... I suppose that would work. But if you're unable to find somewhere/boondocking, it might not work well.
Here's a 600W DC water heater that you could wire directly into your charging system. I'm thinking of drilling a hole in the side one of my water cans and installing this with some rubber gasket/seal. I could then turn it on while driving once my house battery is full.

Another idea is to plumb a line from your heater core and circulate hot coolant through a heat exchanger that is submersed in water. You can buy pre-made devices for this purpose but they are pretty pricey.
I was thinking about getting something like this, then somehow wiring it to my battery but wouldn't know where to begin with that.
