I also have a 2016 Precept 35un and went with the Maxxair II vent covers for both. I chose the black color instead of the white as it matched the AC covers and also really helps to cut down the sunlight and helped keep the kitchen and bathroom cooler. Total install time was less than 1 hour and installation is easy. Once installed, you can have the vents open while driving, which really helps to circulate the air.
