Our previous 5vr had Venetian style blinds and they were a pain in the derriere. We always had to pull them up for travelling and more often than not, when we stopped we found that they had fallen down.The Day/Night shades on our CF30SK are far better.
We can lower the night shade for travelling and it helps keep the inside of our 5vr cooler and they don't flop about. There is one thing that is frustrating about the shades is that they can be difficult to raise and lower. I've found that if you pull the bottom of the shade bar away from the wall a bit, it seems to raise and lower easier. As well, the shade bar must be level or else it will bind and make opening and closing more difficult.
