Love them ,although I would put the black ones over the vent in the bedroom. Don't need extra or early light back there. Also darker if you need a nap in the middle of the day.
We have a 2018 Imaging 2800bh. We have the Camco vent covers over all three of the roof vents. My question is, does anybody leave the vents open during winter storage? I'm thinking no, but I wanted to see what everybody else thoughts were.
