Going on year 2 with my Curtis cab. I have the Curtis II sliding doors, not the Curtis I swing-out doors, on my Yamaha Quiet-Tech gas cart. I had a slight rattle when the doors were closed but the dealer fixed it quickly. They are much warmer and quieter in the cold months than canvas sides. In the warm months they are great with the doors open. When open they do not rattle.
The only recommendation I would make is to have the external rear view mirrors moved down to prevent the blind spot created by the mirror/enclosure wall. When going around a left corner, I have to look under the mirror to check for oncoming traffic. But I’ve gotten pretty good at this now, lol.
