That's going to make a big difference and I bet you won't miss that view when you can be working comfortably! I really like the color on Jane, but what happened to the yellow? Are the stripes a lighter shade, or just a different metallic added?
I inlet a 12K AC/11K Elec heat 240V window unit into the wall of our garage to handle the 110+ summers and hi 20's/low 30's winter nights in Arizona. Since the garage is insulated, inc door, it easily keeps things from freezing in the winter and boiling in the summer. Really doesn't use that much electricity to maintain 60 winters and 80 summers so I could actually work year round. New shop has a 24K minisplit that does both very well, however, running the house garage and shop A/C in the summer is spendy with 6 tons of A/C.
