Follow up on this issue. When I was camping last month, I found the problem. The bottom of the slide is bowed down. I checked the alignment of the slide, and there is about 5/16" between the bottom corners of the slide and the opening it fits into on the bottom; However, when I look in the center, you can see the plywood has bowed down and is dragging in the center.
There are adjustment settings that allow me to lift the slide up from it's current position and will resolve this; However, I can see the bottom continue to sag downwards. I think ultimately I'll run out of adjustment and not be able to lift the slide up anymore.
I'm thinking I might need some sort of roller in the middle to support the slide as it moves in and out; However, the external wall doesn't have enough spacing to allow for a small roller to be mounted.
Any suggestions?
Thanks!
