Wow! I thought I had updated this build more than I did. I got in a rush to get it campable and didn't post any pictures.
To make a long story short, the smoke from Nevada and California came in early last summer. It hit sometime in the first few weeks of June so I went camping with the trailer partially done. I was in the mountains of Idaho and Wyoming from June to October and everything worked great. Even though some of the build was "temporary in nature". Here is one area I was in. I took this picture to get a view of the solar panels, vents, and vent cover.
Then through this winter we were snowed in or gone to visit grandkids, and we didn't get much done then either! Now I am just barely getting started on things, and it will soon be camping time, and I won't be ready again. This build may take awhile longer than I thought.
One of the updates I wanted to mention was my new fan. I had been using a computer fan, and it was great. It was very quiet and had low power usage. I was going to buy another one when I saw the Vortex II fan by Heng. It was reasonably priced, has 3 forward speeds, and 2 reverse. High is 188 CFM and uses 1.18 amps. I am not sure what low uses. Low is quiet, but not as quiet as my computer fan was. It does move a lot more air so I don't have it on for very long. I have had the fan now for almost a year, and I am really pleased with it.
As the picture shows it is mounted so that it is partially in the bathroom area.
