Slide Outs not seating evenly when Extended ????????

I own a 2007 Big Country RL3500.

The Slide that has the Tv and Office extends fully at the bottom but likes an Inch or so at the top to seat against the gaskets.

My question is , How can I adjust it.
I have tried shortning the stoke of the Hydrallic arm by moving the threaded nuts back.
That just makes the bottom not seat then.

I could sure use some help on how to adjust for this.

Read my post about this. Our problem was solved by slackening the awning which was too tight and holding the top in.
