We made it through a relatively hassle free winter! Things went surprisingly well. My wife and I have taken to the full-time Airstream lifestyle and think we are going to stick with it for a while.
Moving forward, there are just a few details that we will be fixing. Although a little nitpicky, if we can manage to fix these few things it will be even better.
Flex hose is a hassle to use to vent sewer gases. It will need to be a more stable semi-permenant solution next year as the slinky nature made it hard to attach for any length of time.
Being able to vent the greenhouse differently would be useful although not for air exchange so much as climate control. The airflow overall was nice and drafty but on those warmer days we roasted even with the doors and windows of the greenhouse open. I am considering fans. The straw bales were great but they are messy and maybe need to be wrapped so it doesn't constantly track into the Airstream. They are worth the mess since it never got below freezing under the Airstream but if it could be cleaner that would be better.
As spring really takes hold, I am going to have to figure out the brakes, axels and hubs before we can go exploring. My wife and I figure that it has wheels and should roll even it is for a stay on another piece of family land or a spin around town. At some point later this year, we will need to head towards Claremont, CA for several months so I can do some research for school. We will need everything to be ship shape for that adventure. Thanks for all the advice, guidance, concerns and support!
