Before everyone starts attacking me about searching for previous posts. I have, and I am not 100% clear.
So this weekend we are going to see a few nights with temperates dipping into the mid 20s for about 2 hours or so. I have a 2020 377 RLBH with climate shield. I am going camping next weekend, and didn't want to do a full winterization. What I did do was open the low point drains, and empty the hot water heater. Is that enough, or do I really need to go and blow every line out? Someone told me that should be fine for a few days as that will allow expansion if needed. What are your thoughts?
