Slide ?

I posted this in the general section with no response so I'll try it here.
While camping last week, I noticed that the bottom of the dinett slide (curb side) had about a 1/2 in. indentation where it slides over the rollers. The street side had a mark on it but only a slight indentation. The rollers are free, and at most there might be 100 lbs.extra weight in the slide evenly distrubited. Any ideas why this is happening or any way to adjust the slide?
Thanks Ed

I read your previous post and admit that i'm usually a little slow to catch on...

Is the indent on the underside of the dinnette?
Do you have any trouble pulling/pushing the slide?
Do you get any resistence when you try to close that end of the TM?

Maybe if you post a pic of the indentation ...

Yes, it is on the underside of the slide. I noticed it when I reached under to turn on the lp tanks. I have not noticed any (more than normal) resistance when pulling the slide out or pushing it in.

Well I can't think of any reason other than pressure/weight from above. We'll be taking our TM out, if not this weekend then in two weeks. I'll take a look at mine to see what kind of wear the underside has.
