Thanks for the additional tips! Snowing pretty well this afternoon, with temps dropping and more snow tonight. I’ve disconnected from city water and have the water filter inside. Campground is shutting off the water tonight and tomorrow night. I greatly appreciate all the advice and comments, thank you.
Update - thank you for the advice, we’re through the coldest stretch with no problems. Sunday night was 27 degrees and we received 5” of snow. Last night it dipped to 25 degrees.
