The other day I saw a 2025 Cougar online and noted that it didn't have the circular diffuser "Blade" AC vents in the ceiling, but rather the old school fixed louvered vents. I did some more digging with some 360° views on the Keystone site and all the 2025 models I looked at do not have those damnable "Blade" vents. I wonder if Keystone finally got the message that they don't work and went back to the proven "technology"? Too late for me since I already went through and replaced all my Blade vents with the louvered ones myself, but good news for those in the market for a new RV!
