Sorry Rob, I don't know why I have so much trouble posting a pic on this forum. I guess I am challenged. It looks like some of the Pic's you posted. I am totally shocked at how poor this Duct is installed on the RW. Also found on the roof. My AC was not pulled down tight agains the gasket. It was sucking hot air in around that gasket. Don't ask me how it had not leaked rain water already.
I've read several threads where people have found the ducting right under the AC messed up and allowing air to flow between the two AC ducting. I guess it's time for me to climb up on the roof and pop the cover off those bad boys and check mine. I know when I first got the RV and if the back AC unit was running when I climbed on the roof and stepped anywhere near the AC it made a vibration noise like the fan was hitting something. It hasn't done that in awhile that I remember, but maybe I should take a look. Thanks all.
Today parked under a cover and completely shielded from the Sun. Yes temps in south Louisiana is 95 degrees with high humidity. It was struggling to keep the temp inside the unit at 78-80 with both AC's running wide open. That is just not acceptable. I think I will put some window units in the side windows about 3 should do it. And then take lots of Pictures and post them online where ever REDWOOD is advertised. Maybe then RW would get serious with a fix. This is sad for a nice unit like this to be this messed up.
