We got snow and some beautiful winter weather with low frost temperatures. To protect the bottom of the caravan against to much cold we collected snow and piled it up against the caravan to close the gab underneath. This way we can keep the wind out and it is a nice hide out for our cats.
We have icicles building on the outside of our windows. The windows do not close nicely everywhere, so there are some gaps. The extreme temperature difference between outside and inside makes for a lot of condensation on the inside of the windows. I need to wipe it of every day, but partially it already runs down the window and makes these nice icicles.
Inside the caravan we have it nice and warm. We still did not need to put the heater on its max. We did encounter some problems though. The drain of our small sink in the back was frozen and we could not use that. Obviously that is not a big issue, since we still have the sink in the kitchen, which did not freeze. A bigger problem was that our water source froze and we could not fetch water. Of course we already expected this and put some extra water in containers in our barn. The warmer wetter came just in time. Our water was used up right at the time we where able to get fresh water again.
