Adding a 3rd A/C Unit

Can anyone tell me if it is possible to add a 3rd a/c unit to the berkshire390 bh... We are having problems with front of the coach never getting cool enough to be comfortable... Last trip was 93 outside and 83 inside....the bedroom is cooler but the main coach is almost unbearable.... the a\c is blowing cool air.... think it might be undersized for the area.... Any suggestions would be much appreciated.

Thanks
Jim

Most units with (2) A/Cs running on Hi can be used to hang meat in! If only cool your A/Cs need serviced And filters cleaned. Prob. not pre wired for 3rd A/C unit. Youroo!!

What steps are you taking to prevent heat/sun from pouring in thru the front windshield? This is a major source of heat in a MH.

Jim,
How year is your rig?
Is the front AC a 15,000 or 13,500 btu?
Maybe your just need it checked. I have a 15,000 up front and it almost freezes us out and I'm talking 95 degrees plus here in AZ.
Mine is a 2012 but.

I also have a issue with getting keeping my MH cool. Last week I added window shades and that will help. The air coming out the a/c is 62 so I think it's functioning correctly and they are both 13500 a/c units. The back one is noisy and I will have the dealer look at it.
Two questions first the a/c cover is painted black and is 20 - 30 degrees hotter than the roof would it make a difference if I painted at least the top white? And second is the a better A/c unit that could replace the Dometic units I have. There web page looks like the make 3 different ones. Anyone with experience with them? I asked the rep at the show last week and he came out to look. He did say the back had a issue with noise and needed to be checked out but it was not worth changing to a 15000 unit. He also was not interested in making suggestions to make the MH cooler.

I have the 2012 390bh... I believe they are both the 13500btu units, they blow cold air like in the 60's... As far as the windows haven't done anything other than keeping the night shades down. It is definitely hot in the drivers section of the coach....
