Air Conditiioning Air Flow Mod

I like part of this modifacation, I think it only makes sence to make sure the take offs for the vent piping are opened up all the way and the edged are all sealed, but I don't think that triangle blocking plate actualy does much aside from getting rid of your dump feature and any slight leakage you might have while that is closed. nowher in a RV is it designed to have laminer flow throughout the piping and to acheive this you would not only have to do the part you did, but you would have to redesign each register point the same way. other wise what ends up happening is you get a slightly better flow untill all the corners and angles in the tracking allow back pressure to build up. I guess if you don't use your dump it doesnt matter much, but with a bigger 5th wheel if no one is in the bedrooms I open the dump during the day to keep the main body of the 5th cooler. but this has got me thinking maybe I'll pull the cover and see how my take offs are.
