I do like this idea of making my own, I have not seen one of these
RVairflow pieces, but my first thought watching the video was that installing those plastic items into the side ports would reduce the open area, thus reducing airflow. I would (will?) use foil tape to smooth the cutout area as required. Figure a good way to seal between the inlet/outlet to prevent a cross-mixing of the two airs. Then maybe use some foam tape to seal between the duct hole and the fabricated insulation board.
The tricky part would be on a good design to use in fabricating the new piece. Any pictures out there?
The other thing is this purchased diverter still seems 'boxy' and may restrict airflow somewhat.
