We wintered in our first Airstream for two full winters. The first location we wintered had a heated post and the second location did not have a heated post. They both had their challenges, but at least having a heated post helps tremendously. Let me explain…..
Our first winter the campground had heated posts for your water. We had a heated hose, but the spigot was not protected/heated and it froze – solid. We had to take a blow dryer to get it to release. Lesson learned. How do you fix this??? Take a Lowes or Home Depot spackle bucket, a metal light clamp that contractors use and a bulb that is heated for your reptilian pets. Put the bucket over the post, clamp the lamp under/inside the bucket with the heated bulb and turn it on. The bucket will automatically tilt, no worries. Your spigot will not freeze, thankfully. You might have to replace the bulb so I would highly recommend buying several of them. The wind bangs the bucket around a bit. You can weight the spackle bucket by tying it down, but it will still bounce around a bit with the wind.
Our second winter the campground did not have a heated post for the water. It was more of a challenge, but we did alright with it. We bought a big blue recycling bucket at Lowes, with the same metal light clamp and several bulbs that are heated. We put a small hole in the “bottom” of the recycling bucket so that it would fit over the top of the post to stay put. We clamped the lamp under/inside the recycling bucket with the heated bulb, remember to buy several of the bulbs. We took lose mulch/dirt/stones and lightly secured the “top” edge of the recycling bucket to the ground and turned the light on. Our post never froze. We did have a heated water hose.
Our biggest challenge was keeping prying eyes out of our set-up. Some would wait till we left and take a look and broke several bulbs in the process. We would have gladly shown anyone our set-up if they had asked. We were the only camper in the campground that had running water the second winter.
On a side note: your heated hose is very heavy and we used a standard hose bib (shown in the picture) that goes into the ground to help keep the heavy heated hose from putting too much stress on the side of the airstream water inlet connection. Just our 02 cents.
Stay warm and enjoy your water for the winter!!
