Paul,

What year model is your coach?

Do you have SCS basement ACs or roof airs?

I have SCS basement ACs in my '99 Newell, and you are right the rear bedroom does not cool down as well as the front.

The difference in the register air and the return air is about same for both units; the front cools slightly better. I think that the reason the bedroom does not cool down is because the air is ducted thru a chaseway that goes from the SCS AC unit in the front of the coach - along the passenger side - thru the mid-bathroom - thru the bedroom and up to the register next to the TV. All of that chaseway area has to be cooled down before the bedroom can be cooled. A great deal of cool air is "warmed" in the process.

When it is 100* + outside about the best you will get inside is 20* difference. It is also very important to close the shades on all windows to stop the sun from warming the inside of the coach. About the only solution is to add a roof AC or two.
