Good morning, everyone! So, I have a bit of a silly question; we just gor our 2019 2800BH, and we can't figure out how to operate the pleated-style blinds. I think that I remember looking at other rigs before we bought this one, and the blinds simply pulled down/pushes up by hand. However, the ones we have are bound by a thread on each side at the bottom to a clear plastic thimble-looking thing that is screwed into the wall. We've had a good laugh about this but would like to know how to use them without damaging anything! Thanks!
