Here is another project of mine.
I got the idea from this guys instructable.
Solar Attic Fan
I took a 15 watt solar panel and then have a 12 volt fan hard wired to the panel.
(Note my solar illuminated safety cone)
Then I installed a MaxAir vent cover over the rear vent and rest the fan on the edge of the slide out.
I have the small crank window behind the stove cranked about halfway open to allow for good air circulation.
