Well, the DW and I are talking about our summer vacation and we would like to go south. But, she does not want to deal with the heat and humidity at night while trying to sleep. I can't blame her! So we are thinking about having an A/C unit installed. Now, I have not done any research yet. What units do you guys have and do you like yours (pros and cons)?? Not sure yet if I want to try to install it myself or bring it to a dealer??? I think the hardest part (Besides cutting the whole in a perfectly good roof) would be lifting the unit up and into place!!! Also, what BTU rating would be good!!
