I ordered this and it would NOT fit correctly in my 28A Fourwinds. The shape of the molded floor and sidewall just would not keep this aligned. Tried several times and it just wouldn't stay aligned which makes it impossible to stay closed. I have it sitting in the garage and FREE to someone that can find a way to use it. The closing groove, imho, didn't work very well and didn't function at all like the video shows. Again, it wasn't aligned for my particular RV but just a heads up for those looking to purchase. I put up a rod and shower curtain and solved all my former issues with accordion door.
