Wow, I am really glad this topic was brought up. I too would like to install wood flooring of some type but was worried that the extra height would mess up the slide. I too have indents from the rollers. Actually, the flooring is actually ripped and has been repaired due to the extra weight on the rollers. The flooring slightly bunches up when the slide is in. I will post pics later. I may have over relooked it, but is there no manual on how to adjust the slide?I emailed Liftco, hopefully they will provide manual. Here is my issue.
