I’m curious how people handle winterization if they plan to use their PUP water system in the fall, and what’s the coldest temperature you feel safe camping with the water system in service. An overnight low that just reaches 32F shouldn’t cause damage, but how low is too low for a night or two? Has anyone put pipe insulation on all their exposed water lines to give yourself extra margin against cold nights while camping? This is my first fall with our NTU pup, and I’m hoping to take another trip, when temperatures could be approaching freezing. My 2007 Fleetwood has PEX tubing with brass fittings, all exposed below the floor. I suppose I could winterize the water system now, and then de-winterize it before the trip if the forecast is promising, but I’m curious how others handle this. Thanks for the advice.
