Avoid frozen water lines?

[dgerfan]

We are scheduled to get gusty winds and single digit temps for a couple days and would like to avoid water line freezing if at all possible. From a quick search of YT most "influencers' have used foam board and foil tape to affix them around the perimeter. I didn't want to pay the premium for the foam board and don't want to toss them once warmer temps come.

I purchased 4 mil plastic sheeting from my small box store, its 10 ft wide so we doubled it over and affixed it to the RV with waterproof foil tape. Folded the slack under the RV and put 4x4 on it. Also put several bags full of leaves around the inner perimeter.

We have lots of propane to run the furnace and plan to fill the fresh tank and use water from it. Also have a digital thermometer to monitor underbelly temps. Is there anything else that you would recommend?

One caution on the bags of leaves, any moisture and they could spontaneously combust. Heated water hose or properly installed heat tape on all exposed fresh water plumbing could also help.

Cover / protect the low point drains.

Stating the obvious, make sure your furnace runs anytime temperatures get down to freezing or below. Maybe not so obvious, I suspect more weight than 2x4s will be needed to hold down the plastic; bricks, blocks, rocks, gallon jugs of water, or even staking the 2x4s into the ground will help.

Also, the tape along the top may not hold if the gusts are strong enough. May want to add some additional tape and maybe even some vertical 2x4s behind the plastic to reduce the "sail" area. The reason foam board is popular is that it is rigid, so that wind gusts pushes it against the side of the trailer and whatever is being used as a bottom anchor. With plastic film, the wind causes the film to bow which results in the film pulling down and away from the trailer at the top and lifting up on the anchor at the bottom.

Looks good. Hope it works well for you.

Don't think you will have to worry about spontaneous combustion.......... But, it would solve the under belly heat problem...lol (sarcasm off)

Thanks everyone for the advice. I have implemented as many as we are able in short notice. Also I placed a brooder light under the RV in front of the spare tire to hopefully prevent the kitchen lines from freezing. I will only turn it on if temperature sensor in the underbelly reads under 35F.

I have seen theses used to cover the low point drains, and the fresh water tank valve (white one)
