I have a 22' four winns with a cuddy cabin. I am looking for a cheaper alternative to air condition other than the ones that drop in the hatch. I have two side by side doors on my cabin. I was thinking of taking one off and building a little wall with a window unit air conditioner in it and mount it where the door was. There would be plenty of room to use the other door. And my generator has enough power to run the a/c unit. The space is big enough to fit the window unit. What does everybody think about this idea? Has anybody tried it? Can anyone think of potential problems?
