I have the smaller version installed in my van. One on each side. The issue I could see with the larger version is that the curve of the sheet metal becomes much more of an issue. Window is flat, body panel is curved. Its noticeable on my windows, but only if you are looking. Sure you can bridge the gap with the adhesive but it will be just that much more noticeable. You will see a larger gap on the top and bottom of the window and any messiness of the install will be there for the world to see. The mistake I made with my install was that I got a bit too liberal with the primer and the window didn't fully cover it.
