I saw an old "boat-mobile" of a car a while back with a window AC unit mounted in the passenger side rear window, with a big honking Briggs generator running in the trunk. Driving through the city with his trunk lid open so the generator could breathe. I was behind him at a stop light, and could hear that generator roaring over the stereo in my car with the windows up. Looked like the window unit was mainly being held in place with Gorilla tape. You just can't make this stuff up.......these people are out there! Lol!
