So we just purchased our new ST262BH last year. I was surprised to see our unit came with Wood faux Blinds. While out on our first trip my Wife noticed when she spun the long handle the blinds would neither open or close, apparently this was the issue on all 4 of our blinds. So me being me I grabbed my screwgun and removed the window treatments and was blown away by what I saw.
Apparently the rocket scientists who assembled our Trailer didn't use any type of bracket to fasten the blinds, instead they chose to ram a screw through the blinds and right into the window frame. The issue was the screw was putting pressure on a small shaft connected to the crank handle and preventing it from turning properly.
I ended up fixing this by drilling holes below the original screw holes, adding a thick washer behind the blind and screwed them back into place.
The Washer allowed the louvers pull away from the window frame and float a little better.
