Winter Camping in Jayflight 32BHDS w/ Thermal Package

I have never camped with day time temps that cold but plenty of over night temps down into the low 20's. We use one of the small upright slim heaters running off electricity. It actually heats the camper better than the furnace. I could run both and I think it would be fine. As mentioned earlier, I would certainly dump some anti freeze in the tanks.
