Need To Adjust The Slide-Out On A Salem TT ?

I have a 2003 Salem LE 29-BHSS by Forest River. . The slide-out has the dinette and the sofa.

The slide-out needs adjusted so it will fit better when its in. . On the left side, its against the wall and the top is too.

On the right side its against the wall, but the top is out about 2-1/2 inches.

Does anyone have a link on how to adjust the slide-out ?

This is my first TT with a slide-out, and I don't know what to adjust.

I can take pictures if needed.

Thanks!
