I have a 16k BTU unit and it works just adequately on super hot days. I do have the option of overspeeding the compressor at a major cost of power when it gets really hot inside. I would think the 9k pioneer unit would be great for any state where outdoor temps do not exceed 90º. The buildup of interior heat of our coaches would preclude any cooling gains.
