I'm in the category of disliking the monochromatic color scheme of the interior and found some blinds on Amazon that suited me better.
I also had difficulty raising and lowering the blinds with one hand, especially at an angle. They were so stiff.
New blinds are much lighter and can be adjusted with much effort and that annoying metal corner is gone.
A woman's hair clip at the top keep them from swinging to and fro on the road, if need be.
I removed all the stock valances, like others have done, and added colorful curtains on the other end as well. I kept the blinds because I don't use that end of the trailer.
Much more cozy.
