Mine clamps to the roof. Pull the inside A/C shroud and you'll probably see the fasteners going up from below. There is nothing on the top side involved in holding mine on.
i Think I have what they call a race track type plenum where both AC units dump into the same duct. Either AC unit can supply the whole coach but when both are working I have much stronger air flow. I like the design but all I have on the inside are small round supply registers and 4 small rectangular return ducts no where close to where the AC units are. The mounting bolts have to be outside under the shrouds.
