I agree about the hassle for sure. I was hoping there might be another H27 owner out there who has either added AC themselves or had it added so I could see how and where it was installed. I would hate to spend that much and then do a poor installation.You need to add AC and no ventilation improvement is going to help and yes I use
my AC to cool down the boat and at night run fans for sleeping.
I do have friends that put window unit in Compainway opening,pain in the ass but it works and saves $$$$. but a pain getting in and out.
