Too hot inside enclosed trailer

[ultrarider]

I thought I would share what I made to keep the inside of the trailer temperature manageable.
1. I made this screen to install into the front hatch, which is hinged so the sides fold down for storage.
2. I bought two $6.00 fans at Walmart and mounted them on the inside of the screen to bring in air
3. I bought two Muffin (computer fans) on Amazon and mounted them inside at the side vents to exhaust the ceiling height trapped hot air out.
4. I bought a "Inkbird" temperature controller on Amazon to turn the fans on & off at set temperature. Located the Thermocoupler 1" off the ceiling
Here are a few pics.
