phoenix2015 Report post Posted November 29, 2016 I have a 2005 Beaver Santiam 40 PDQ. Is the ductwork on front and rear roof top a/c units one piece or is it 2 separate ductwork systems? I would like to only run front unit when sleeping and rear unit on when watching TV, etc. barryair457@bellsouth.net Share this post Link to post Share on other sites

In most coaches, the duct work is interconnected/one long duct, so running the front roof A/C and closing the front vents will cool the back. Try it and let us know what you find. The other option is to contact Monaco, as they built the coach. Share this post Link to post Share on other sites
