We are camped in the Grand Canyon for the winter. We will be working in the Association bookstores and are looking forward to the season in the canyon.
I have attached some photos of our set up. The first is just before I started skirting the trailer for the winter. The last three show the trailer with my skirting job and the back side with my winterized hose and such. The vertical post is the water inlet and I winterized it as well..no point taking a chance.
I used 3/4 inch foam board that is foil sided (out to match the Airstream
The installation is on a gravel pad, so there was a fair amount of trimming and cutting to get it all to fit properly. The foam board is forced up under the rub rail and then taped. I decided to apply as little tape to the trailer as possible. I am sure that I will have to do some pretty serious cleaning of the rub rail in the spring, but it looked like the safest and easiest solution for our installation.
The weather last night was clear and 17 degrees. I suspect that at 7000 feet plus or minus..we will see some temperatures near zero this winter.
One thing that you cannot see is that I put a trouble light under the trailer that I can turn on when the temps get really cold..I am looking for a thermostat that I can hook up to do it automatically..but if I need to I will just plug it in when needed.
I did look at fabric skirting. It would be pretty simple, but I just could not justify the money for what may turn out to be a single season experiment. I will look at fabric again if we decide to do another winter up here.
