If I recall (BIL had a 23B) you have a sofa slide and isn't as deep as the standard TT slides. Most folks have a RV technician perform slide adjustments because not all slides are created equal, and if adjusted incorrectly damage can be incurred.
The following link describes a typical slide adjustment, but may not represent the same hardware mechanism that the 23B uses;

Here's a slide adjustment video by Lippert Components who manufactures many slides for the RV industry (may not represent the 23B slide mechanism):
Oh, I believe the 23B utilizes a "transit bar", be sure to use it whenever the slide is closed to avoid any slide movement during transit.
