The design didn't work, which is why they now roof mount the ac. I'm just trying to figure out how to get it to cool better than it does now. It's wedged in with no air space on either side or on the top. There is a baffle, but it only separates the exhaust from the rest of the ac.
Here is a picture that shows the problem. The ac is crammed in this hole under the seat until the rear of ac is pushed through the divider creating a hot area behind it. There is no obvious way to get air to the side vents from the outside.
They went to a lot of trouble to make a hole in the floor and have it open under the trailer and covered with a screen, but since there are no vents in the bottom of the ac, very little air can flow from under the ac to the side vents.
