This is a WONDERFUL thread. Thank you so much for all the great tips. I have 2 AC units in my Windsport 29M, so I'm already in pretty good shape. Yet, I have a hard time keeping my hands off if I find a way to 'fix' things to work a little better. So, I'm definitely going to take a close look at my duct work and apply the tips here to make it more efficient. Insulating the low pressure portion of the AC is on my list too.

To help with airflow while driving, how about a scoop/deflector on each side of the cover to pull air in and help the condenser cool? Anyone tried that? I know some here have added fans.

Way way back a guy (post #72 in this thread by gmtech16450yz) had pulled & remounted his AC unit backwards to deal with the airflow problem while driving. I wonder why RV manufacturers don't do this as a standard practice? It would not cost more.

Thats, Im glad its helping folks.

I dont think mounting backwards would do any good unless you change the rotation on the fan (The Fan under the roof cover). Its blowing out (on the condenser) to remove heat so the would be fighting each other. But the scoops might help.

I though about changing the plastic cover on mine.... the louvers restrict the outbound air on the back of the cover. Might see a small inpovement there.

IMO, I think with all of the "easy" mods listed here there is no need to add fans or reverse the AC on the roof.

Im happy with my results - No need for 2nd AC on my short 27 foot RV.
