I wouldn't even go a second a/c. It's all about how how you shade your rv from the sun no matter if you have one or two ac units. It was an definitely an RV learning curve for me coming from up north to the south. It's not just the fact that your rv is a dark color.

Just putting pillow inserts in all your Roof vents will drop the temp inside by over 10 degrees. Sunshades in windshield and side windows and cover off the cab area = another drop of 10+ degrees inside the coach. On real hot days parked or traveling I even cover the skylights makes a BIG difference.

Parking your coach with the awning side to the west and dropping that awning to it's lower position helps cool it down in the hot afternoon.
This is one of the main reasons I don't buy coaches with auto awnings because you can't drop them down as low to keep the sun from heating up the side.

YOU have to help these poor RV a/c units that are struggling to keep a coach cool with tons of windows that are not thermopane and uninsulated roof/walls!!

Also, Depending where you have been RV'ing cleaning those coils OFTEN make even a bigger difference how cool it keeps your RV. Up North I never cleaned them, when down in Florida? I have them cleaned every couple of months. High humidity, green mold, pollen all contribute to build up in a heartbeat on the coils. Just saying, that's what I have learned about RV A/C 101! :B

Its exactly what we do, but still not enough. All you have to do is open a door and its all over, LOL.

Ok, been there done that! We have the identical Concord as you do--same year model, everything. We had our dealer upgrade our AC to 15,000 after about 6 months. It may have helped a little, but not near enough. We are now considering adding another AC. Yes, I know we only have 30 amps, but we will have to plug in to the pedestal to the 20 amp plug separately. Living in Texas we don't use ours much in the summer. It is just too hot! We park in the shade and cover the skylights in reflectix and also the cab area. We also use fans to move the air around.

If I had to do it all over again, I would have kept my 13,500 and just added and additional AC instead of replacing the one I already had. I hope this helps. Other than our AC issue and heat in Texas, we love our coach.

I have all the windows, skylights, vents, and anything else covered it looks like night in the MH all the time. I clean the coils about once a month. Still has hard time keeping up. But if the 15,000 isn't going to be much better then I will have to look at another option. A second unit is out though. The only available vent left is right behind the other air unit which would put them back to back. Thanks for all the feed back. Saved me some time and $$$$$$.

Well Here's the last thing I added when I decided to stay, in of all places, 'Florida' for the 'summer'!!

I added a portable de-humidifier per the advice of my RV mobile Florida Repairman.

The dehumidifier really made a big difference how cold it got inside the coach. My a/c said thank you for the help.
