Thanks for the kind words.
The rear 6 inch duct is a very tight fit. I had expected to add a metal rectangular to round transition piece (recommended by the Oklahoma dealer and RV Comfort Systems) but my trailer already had it installed.
I was able to connect the rear 6" duct to the front side of the plenum, but the duct is compressed quite a bit. The airflow is not as much as the other 6" fed floor registers, but some is coming out.
I'm thinking of fabricating a new plenum with the back 6" duct connection moved to the side of the housing. which will remove the need for the 180 degree duct bend. I plan to see how it works over the next few months. We are in Arizona for a few months, and the morning lows are around 40 degrees. It is working great so far. In May, we will be back to Creede where the morning low temps will likely be in the teens. That will be a better test, and will determine if I fabricate a new plenum with the side 6 inch duct feed.
