After a prolonged stay in a large garage, Grey Matter is back! We’re very lucky to have a relative with a large garage who also loves to build vehicles from scratch! A friendly face of a steel bench watched over the work.
The fan was the first (and easiest) to go in.
We will wait and attach the inside plastic mount for the fan when the inside ceiling is installed. 
A kit from Hein (DIYvan.com http://stores.ebay.com/impactp
was helpful to attach the rails which will hold the solar panels.

Attaching the solar panels to the rails was a little tricky, requiring a ‘please help’ email to Hein. After he explained, they went on easy enough. The solar panels don’t have a lot of space under the edge, so it took a bit of fussing. 
One down, one to go!
The curved opening for the new side window gave Bob a bit of anxiety before cutting, but it fit perfectly! 
The wood required to fit out the thickness needed a little more thickness added to make a snug fit. (Note: after getting it home, we found a slight leak, so we’ll need to remove and reseal it.)
The air conditioner was my biggest concern – the framing and getting it installed with its weight needed to be carefully pulled off. After doing the inside framing, we had questions about how to install the heat element on the ac. Apparently, one needed piece had dropped inside the ac. Bob finally figured it out, and he and a friend got it installed and done! Yay!
A few more minor jobs, and it was on its way home!
Upstate New York! Typical winter weather
Next project is completing the electric diagram and layout plans. This has changed from the original idea, so stay tuned for that update!
Much appreciation and gratitude to Bob for all of his help with this.
