In this video, I show how an RV Airflow Systems kit is installed on a shallow plenum Winnebago Roof. It is not a direct fit, and small modifications have to be made for the kit to fit. I also show the air flow speed comparison from the DIY kit to the RV Airflow. To make the RV Airflow kit even better for the Winnebago roof, they could use 1/4 inch taller duct inserts as well as making the foam 1/4 inch thicker and making the openings of the RV airflow 1/4 inch taller to utilize the full airflow. Seems there is enough room in the plenum.

You will have to check my math on the % increase, but all the numbers are shown in the video.
I bought directly from RV Airflow. The part is called "RV Airflow for Coleman Mach 3, 10, 15, Q Shallow Plenum". You can find discount codes from bigger YouTube Channels.
