I installed mine because my slides don't have a top flange and I use them to prevent water intrusion when the slides are closed. Came to appreciate them more when they rolled off a sheet of ice at Yellowstone. The ice would have certainly slid under the slide wipers and melted inside the trailer. In my mind they are "no brainer" conveniences which are worth the effort and expense. If your headboard is inside a slide the slide topper will make it quieter inside during a hard rain. I'm keeping mine.
