In an effort to give you some feedback I thought I’d share my experience with AC. I didn’t try this unit but I did instal a Portable AC like you can purchase at Lowe’s etc.. I ran the exhaust out under the gunwal by the rod holder holes. I think it was a 9K BTU unit and it would never cool the cabin more than about 10 degrees lower than the outside temp. Long story short, I ended up installing a regular marine 5K BTU Webasto FCF unit. That cools the cabin very well. Remember, that unit has exhaust tubes and you will need to get that hot air out of the cabin. I googled the unit and assume I saw the one you are looking at?
