Rockwood Roo 23ss Slide out box shifted forward, can this be adjusted?

[mikeandkimcamp]

We have a 2008 Rockwood Roo 23SS. It has a Universal Slide from MTech Corp.

We have been having problems with our slide out sticking on the top, and needing a gentle nudge, to get it to slide out evenly with the botton. After it is extended all the way on its own, it needs another nudge to get the kitchen/sofa on the botton to extend all the way out, so its even with the top, and not leaning.

Upon further inspection, we noticed that the entire box has shifted an inch or two towards the front of the camper. In other words, the rubber slide gasket in the front of the slide out, that gently wipes the box going in, and coming out, is mashed up against the slide out box, while the rear isn't mashed at all.
Maybe this shifting has slightly bent the rails, causing the slide out issues stated above?

Does anyone know if the slide out box with a Universal Slide out can be adjusted side to side an inch or two?

Sure would like to know if other Roo owners have had their slide out boxes shift, and how they remedied this.
