@sourdough & @wiredgeorge .....the sawsall> now that's funny![emoji6], although I do own a Milwaukee [emoji106]
I do not have dual zone thermostats....just changed out the Colemans to digital.
The bedroom is plumbed for blasting and or for a huge hairdryer? None the less you could hang beef in their> a good thing : blush:
I called a RV service Tech and actually found one that was pretty knowledgeable...yeah suprised me too.
It sounds like it could be " Rocket Science"... maybe it can be done, maybe not...bring it in we'll look it over kinda thing.
It's also possible that that bedroom AC could cause some turbulence like Sourdough mentioned.....
I also was told that since I'm in AZ having a 15k vs a 13.5k AC unit wouldn't make a whole lot of difference?>ok[emoji848]
Sounds like a lot of work...
