Something stuck under slideout?

Hi, I'm new to this forum and have found it informative, thanks. I now have a problem that I'm not sure how to resolve.

When fully extended out my slide out floor is raised in the middle as if somthing is stuck under it near the inside edge, we have a table and chairs and can clearly see that the chair near the centre of the slidout is leaning towards the wall.
I've had a look under the slide out but can't get access to see anything. I've also looked inside and the bull nose edge of the slide out is raised off the plastic rubbing strip but not enouge to see or probe for anything. When I wind the slide in it tilts befor coming in and I think this gives it enough clearance to clear the object that is causing the problem.

Is there a way of raising the inside edge of the slide out to check that it's all clear?

Sounds like the slide may be out of adjustment. If there is something under neath have you tried looking under the slide floor from the inside when it raises to come in. Mine has a gap between the slide and the floor. Maybe run it in a few inches and check it.
