Pleated shades, should I tow with them up or down?

During our first year with our fifth wheel, a string broke on our large rear window's pleated shade. It was under warranty, so we took it to the dealer for repair. Well, they will just replace it and they had our rig for over 2 months for it.
We have since had several more break, so I watched YouTube videos, bought a repair kit from the dealer and fixed them myself. Once you understand how they work, it's pretty easy. Like someone above said, you get to be a pro at it.
