I had to adjust my own slide, It is really easy to do. If you have a Lippert frame, it will show you how to do it in your Manuel or get it off the internet. When I got my unit the decals all lined up. After some use I noticed that the decals where off by a good inch.I told them the side fell on the left side of the unit. They told me they adjusted it and it still looked the same to me. When I got home I readjusted it to even the decals. I had to pick up the left side. It was easy to do. You can adjust the stop and up and down with a few tools. It should seal TIGHT when pulled in. Your seal is more then just a DUST seal. Now it also moves in and out a lot easier and it is not binding.
