Does your house AC have rectangular ducts going to the vents? Although I haven’t gotten into mine, I was under the impression they used flex-duct from the house AC to the vents. And, when you said you were going to insulate the cap, do you mean the “brow” in the cab? I apologize for the newbie questions but inquiring minds want to know.
Thanks Steamboat

No they do not use flex duct, when the roof is made they rout out the AC tunnels in the styrofoam to make ducts or they lay them up with strips of stryofoam. I included a pic from their brochure, although they show they put aluminum ducts in none of mine are, they are just cut out. Simply take the 4 screws out of one of your rounds ducts and look at the cavity and you will get a pretty clear picture. There is no need for the duct to go past that last duct behind the drivers seat. No you could add an additional duct above the drivers seat by cutting it in and then blocking the duct from going into the cap there.

Remember, the pictures I posted previously rotated on upload so turn your screen to get a better feel for it. The very last picture is looking down the bedroom duct towards the rear cap.
