We live in STL as well...
our rule of thumb, if its too hot or cold to go outside and play, we have more room and more channels at our house.
We are planning on going camping this weekend and possibly thanksgiving weekend but will probably shut the camper up after that. Shower / restrooms close the week of thanksgiving or after in MO and in Illinois.
Staying warm with your furnace (or use an electric heater to save propane) is the easy part, the hard part is dealing with the freezing tanks water supplies etc
