I could not believe all the stuff I got out of there. Even screws and misc. construction garbage. Too bad they cannot do a bit of cleanup when constructing these campers. Open a few panels on your walls and u will find all kinds of stuff. And the guy who put the rubber sealer around my air conditioning unit on the roof and the other vents must have had his head up his rear. He did the job but sprayed the stuff all over and it looks like crap. Only discovered it when I got on the roof of my unit. It is purely cosmetic but if you are going to do a job why not take pride in it and do it right?
Thanks ham camper.
I was just thinking if the additional bedroom AC could duct into the existing bedroom duct work, then it could add more pressure to all the other existing vents.
The dealer or installer probably just installs at the skylight location and the new unit then blows straight down.
