how about driving around in the back seat of an old van, and putting your hands on the drivers’ eyes just for fun? while a buddy in the passenger seat tries to steer?
Yeah, that would work. 
I slept through the winter in Rangely, Colorado in an uninsulated nonelectrified wooden shack used to take tickets for a rodeo during summer months. I had a serious camper’s down sleeping bag rated for - 40°. Rangely sometimes got down to temps not far above that. I had a heavy down jacket and I slept in my clothes. On some nights I slept in damn near ALL of my clothes, or as many as I could put on at the same time, and I daresay “rated for -40°” means “you will probably survive the experience”, not “you will be cozy and comfortable”.
You cope with what you must cope with.
Well, back in the day, we did it with kerosene Heaters. We had wick lighted Kerosene Heaters, that could easily put out enough raw BTU’s to heat a room. That was in the 80’s. But now the kersosene pumps are far and few between at the gas Stations. I suppose the niche has been overtaken by the ironic, “Electric Amish Heaters”. Faux fireplace electric Heaters with an Amish providence and name… if I were an Anabaptist Bishop I might be at least peeved.
I am seriously disturbed about how far we have come from the Kerosene heaters, because we can’t depend on the Electric Grid… they should be reintroduced as last line and practical heating meeasures. For someone like the Op this is a practical and safe alternative.
