If this has been asked before I am sorry. I did use the search both on the forums as well as Google and did not find much. We just got back from a great trip. During the trip as I was running the glides out I noticed a popping/cracking noise from the front room slide. Upon inspection there is a plastic corner piece on the edge of the slide. Looks like a small plastic angle piece. This has cracked and broken. Has anyone else had this happen. Looks to run the whole width of the slide. My main concern is water damage occurring. Here is a picture.
