Slide Adjustment Q

[Diesel-Gypsy]

I would like to adjust the dinette-slide a little.
The slide when closed is almost 3/4" in further at the top, than the bottom.
The difference is progressive from the bottom up to the top.
The bottom of the slide-out is flush with the trailer wall.

That white rubber bulb seal is completely squashed-flat at the top, within 2 1/2 feet towards the bottom, it is normal.

I see the large bolts under the slide, but I cannot really figure out which one will allow me to angle the top of the slide outward.

Anybody on this board savvy enough to help out?

I have the electric slides, but I think the adjusters might be the same as the lippert slides.

Thanks in advance.
