We got rid of the DuoTherm HP/AC in our 30' Classic. It was inadequate and extremely noisy. We replaced it with an AirExcel 15K model AC only. It is quieter and cools the entire trailer in 90*+ heat. The con for us was no easy way to route the condensate. I ended up having an aluminum pan made that the AC sits in on the roof with a way to route the condensate into the original down-thru-the-wall hoses. Wish I had taken pics but it's too late for that.
