Creekside Outdoors RV owners - freezing temps

My weekender is not nearly as nice as your creekside and I do a 10 day elk hunt where oftent the highs are just above freezing. Mine has done ok, the only issue was the first year I had left the bathroom door clsed and the line got a bit of ice in it where if feeds the toilet. By the tiem we had arrived back form the morning hunt witht he thermostat left at 50 and the door open it was free flowing again. I think you would be fine as long as you were not parking it and leavig for a week or two with no heat inside.
