Maybe one of us has a slide out of adjustment. When mine comes in, the very first thing is the bottom lifts up. This tilts the slide so the top is tilted outwards.
As the slide comes in, the slide "topples" into the camper slightly as the center of gravity of the slide passes the 1/2 way point. This releases the weight on the spring loaded pinion gear tracking assemblies.
In this configuration, the top of the slide may contact the wall first but there is very little pressure to compress the top seals. Continued running of the motor pulls the bottom in until the bottom of the slide hits the outer wall.
The top seal in mine now rests on the outer wall but is not tight (though the bottom is).
When I install the slide brace (as in the photo), as I tighten the brace, the top pulls in compressing the top seal (light that was visible in the corners is extinguished) and the slide rotates slightly into the camper re-compressing the pinion gear spring pack.
Note: There is a clutch in the motor driven gear pack that can release (and in fact does so every time you reach full extension and retraction - that clacking noise). If the slide does not have the transit bars in place, a sharp enough shock can unlatch that clutch and allow the slide to move. Once in motion the weight of the slide may very well allow the slide to continue to full extension.
