We tried putting the jerry cans into the back of the truck -- they froze there, too. And we had a cooler in the back of the truck -- we took all the food out of it but left water bottles inside. They froze.
I like the idea of bringing in one jerry can and leaving it just inside the doorway -- that is all we would have room for. No way we can put a can in the shower -- there is no room. In our trailer, the shower is the toilet, too!
A couple of years ago, I enclosed the area that froze (the low point of the tank, where the outflow tube is attached), and that area is wrapped in reflectix. That method was adequate when the temp was around 20 degrees, but not at 10 degrees.
I am thinking about creating a fully enclosed air space around the tubing, with an LED panel inside that space. The "dead air" zone around the tube would be small. The LED would give off just enough heat, I think, to warm the trapped air just a little, enough to get us through the night without freezing. (I could easily monitor the temp with my remote thermometer, which I now use to monitor my backyard smoker!)
I would power the LED by tapping into my 12 volt system, with a switch. It would not draw much power -- maybe 300 milliamps. The only trick would be to remember to shut it off in the morning!!
Forget the LEDs. They don't produce heat.
