I went out and moved the rugs DW now has under the sofa and put the slide out......
Then I moved the sofa in about 1/2 way.......
And lastly, I moved the sofa all the way in. The small water bottle is directly across from where the dent is......
So, as you can see, the little brown plastic slide does not directly rest where the dent/rip is located. HOWEREVER! What I did notice was as the slide was going out, the front dips down for several inches before coming back up and staying up as the slide traverses out.
