2nd AC recommendations?

[FLButler3]

Hi all. I have a 2021 Eagle 31MB and am looking to add a 2nd AC to the bedroom. The coach is prewired for it and I am kicking myself for not insisting on it at the time of purchase. Oh well, live and learn.

I am looking for recommendations on what brands and models I should be looking at. It will be non-ducted and I would prefer something that isn't too loud.

We have the low profile Coleman Mach 8 15K BTUs, two of them for our 43 foot FVR, they are fairly quiet compared to others I have seen/heard....they can be ducted or not...the one pin our bedroom was ducted with ceiling vent accessible from inside the RV. I added the RV Air Flow Plenum kit so all the air goes into the ducts and the return from the ceiling cover...it is now a little quieter as well...
However, they are still a little loud, especially on high...on low setting can barely tell they are on.... at least ours are.
