I just bought a 2020 5 seat model X for the larger rear cargo area. We have a Great Pyrenees and we need room for her. My concern was insuring that she is getting cool air. Can I purchase the interior panels associated with the 6 and 7 seat configuration and somehow connect to the air conditioner. I doubt that there is a separate fan just for the rear cargo/3rd row seat, but really don’t know. Any help would be appreciated.
