I have a 1995 coleman fleetwood "utha" popup.It does not have a/c. I was reading here on the net and I see that people have put them in on the side of there camper.The only problem I have is that my side windows unzipper from the top down.The one side connects to the screen door and the otherside is connect to the bunk side. I dont know if my roof will hold a rv a/c. I dont want to cut a hole in the back of the camper because thats where the converter is.Is there a way to put one in the side window or somewhere? Is there any one with the same camper that had this problem.If there is anything I can do to have a/c please let me know and if anyone has pictures please help me on this.
