Camping in sub freezing weather

We camp in cold weather, but I winterize the camper and buy windshield washer fluid to flush the toilet. We bring bottled water to drink and make coffee. I have fixed broken plumbing in a camper before and getting to some of the fittings is a pain. So we don't take any chances.

Same for us - even though RVs boast about "heated tanks" - most dump pipes and low-point drains are still exposed to the cold. We regularly camped in sub-freezing temps as we traveled from Michigan to Florida in January. Our black and gray tanks were exposed to the cold (no heaters) and we never had any problems as long as ample antifreeze was dumped down the drains. Obviously, we used the campground showers.
