Have the same system in my plane and when living in the hotter temps of the southern United States, this is a much appreciated addition. I grew up in Mahomet, IL (near Champaign-Urbana), and can attest to the heat/humidity of the mid-west also. Had the AC controls mounted into the lower panel. Ordered the dual pump system for the temps in Phoenix, AZ.
Trying to come up with a design for distribution of the air with shut-off options for passengers (instead of the 2 large flex pipes), but haven't come up with a design that will easily fit and be cosmetically appealing, be safe, and be easily removed.
