I have a typical 7x16 enclosed trailer, ramp door on the back and side down on the right side, square crank up vent in the middle of the roof. Problem is my blowers, and water cooler, everything is in the trailer, so I am in and out of the trailer several times per stop and all day long. In the winter time it is okay, but in the summer it gets downright hot inside the trailer. Been wanting a way to vent more air into the front area of the trailer without having to open the side door at each stop. Ideas? Products I should look at?
