Thinking about adding a third to ours, and debating to duct or not to duct. 2 just don't keep up in this 40 footer. At least not to my likings. It's been 90-95 on occasion, and you might see 74 in the living room. I still have a few more mods to do for improvement before I take the plunge on a third. Only have 2 ducts in the biggest room (living room). I've added deflectors in each AC to direct the air flow directly into the ducting. This improved air flow. Added scoops to the living room ducts. Definitely helped. Now going to add 2 more outlets in the living room, and baffle off the ends of each duct. Then, we'll see how it does. The "circular" duct system cedar creek does makes no sense at all.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
