As most of you know we are installing a heating and cooling system in our Columbia 34. I have having a hard time on how to run the duct work I am considering using the wall cavity (like used in houses) as my duct run since it will be difficult to run any ducts or flex pipe to this location.
I my picture below you can see a hatch pattern the represents a board that I would like to install to make the air run in the wall cavity, and how the air will be let out of the space through some custom window boxes in the areas the previous owner made to install some port windows. The unit is gettting installed in a locker fwd (to the right in these pictures) of the couch, there is no problem running the duct work fwd into the v-berth.
Is this a bad plan, anyone see a better way to to this? I want to do it the best way possible.
