Yes, at night you still need to use your privacy curtains.
My neighbor had the Sunguard shades setup on his motorhome. They do work.
I liked the idea of the shade, daytime visibility and privacy, but I'm not too fond of drilling holes to install the snaps that fasten it to the coach.
There is another brand, (Magneshade), that uses magnets, that I may eventually entertain, (or eventually figure out how to make my own).
