Ducting on 2 AC unit - 2015 30T Vista/Sunstar motorhome

[Lakejumper]

Does anyone know if the front AC is ducted to the bedroom on the Winnebago/Itasca with two ACs? I'd like to know if it will cool down the bedroom when you don't have enough power to run them both.
Thanks!

Yes the front is ducted to the back but in real hot weather or parked in the full sun you will need the rear also. Chuck

I'd have to check each vent to be completely accurate, but I believe that some of the A/C vents in the rear bedroom are from the front A/C and some are from the rear A/C unit, or at least that is the case on my 2005 34A. When both A/C units are on, you can freeze in the bedroom, in part of course because it's a smaller area to cool. I believe the rear A/C also cools the water closet too, and not the front A/C. -RT

Thank you for the quick responses. This is very helpful.

In my 2011 Suncruiser 32h, both A/C units vent through the same ducting. Same is true for the return ducting. As another member indicated, when the weather is really hot, both A/C units are needed to cool down the coach.

This is helpful info. I plan on getting a 50 amp unit with two ACs if possible.

I looked at the RV again today and ran both ACs. On this particular unit, I found that the front AC blows air out of one of the bedroom ducts. The remaining two bedroom ducts are connected to the rear (2nd) AC.
