Tried to install some AVS in channel vent shades tonight with little success. For whatever reason I could not get the shade up into the track far enough. Had AVS for my '12 Trail and they were fine. The fitment guide on Amazon showed good for the 2021, but the part that arrived read 2010 to 2020. I doubt the window tracks have changed much, but who knows. Anyone had success with AVS or other brands on a 2021?
