Ducting 2nd AC

I have a Sunset Trail ss-291rk with 15k main ducted ac and 13.5k not ducted bedroom ac. The problem we have is in 90+ degree weather the main part of the rv will get very warm and the bedroom will stay cold. We try to use a fan to blow the air from the bedroom, but because of the layout, it's hard to get good airflow. There is a ac vent from the main ac right next to the bedroom ac, my thought is that that I could tie into that ac duct and get both ac's to go through the ducts.

Things I'm guessing I would need to do to accomplish this:
-Buy a coleman ducted kit like the one on the main ac.
-Make or buy an 8" long duct to go from the bedroom ac to that vent. (It looks like there's a direct path in the ceiling)
- I may need to cut more ac vents?

Does anyone have the second AC install that is ducted like this? It seems like it would work, but i might be missing something. Most rv's that have both ac's ducted seem to come set up like this from the factory.

Ducting 2nd AC

I went the route of buying adjustable vents for my bedroom and bathroom and shutting them closed. My bedroom AC cools the bedroom and bath and the main now pushes more cold air into the main living area.

Alex, where did you order the adjustable vent covers? I think I'd like to do the same to close off my bathroom vent.

I may not understand exactly what you are asking, but I am going to say this...You have two AC units in your camper...One in the main living area and one in the bedroom...The one in the main living area is ducted and not totally cooling that area...My question is does that AC unit in the main living area have a DUMP, that switches the air from going through the duct work and dumps the cool air directly into the main living area...??? If so I think I would just do that as opposed to going through all the trouble of ducting the bedroom AC unit...IMHO...
