There's an image below that describes the window shade in more detail. The Inverter is a Wagan Elite 400W Pro #2601. I really like it. It's pure sine which I needed for my laptop and is very quiet (aside from a loud beep when I turn it off). The fan only runs on really hot days after extended use. No chirping.great build! Can you explain how you made the rear window shades and how they stay in place? Also, I see the Wagan 400w inverter. How do you like it? I had a lower powered one that chirped under load and was thinking of getting a beefier one.
