We were down in the low 30's at night most of Jan and Feb 2014 at night. We have Three elec heater's running and that was enough to keep inside at 68-72 deg. Elec is included in our site costs per month. We got down to 35 last night and our furnace did not kick on all night. The elec heaters were set at 67 and I could hear them shutting on and off during the night. We only use the propane to cook and most of the time wife uses the convection oven. I did run to cords in from the pole to power two of the heaters that way we do not have to worry about shutting off a breaker.
