2008 Jayco 1207. Right rear will not raise. I removed the dinette seat covering this area and discovered this:
This is what the front right (undamaged) looks like:
So clearly something caused the rear one to bind up. I noticed it wasn't going up when the other 3 corners were up maybe an inch.
This doesn't appear to be something that just suddenly happened.. I get the feeling perhaps it had been happening over time and finally reached the completely bound/pinched condition in the photo.
So, any idea how this might have happened? Happen to anyone else? Is it a difficult fix?
