Joe, the slide out can be adjusted but you will need to adjust, not only the outside but also the inside, to keep from twisting the slide out room. There are adjustment slots and bolts on the rams attached to the outside wall under the room. When dropping or raising the floor line you will need to also do the same on the inside floor on this end of the room. You probably have rollers that may not be easily adjustable but putting down a slide out slider (flat nylon pad) that the roller can roll up onto the floor on the end that needs raising can accomplish the task. How mechanically minded and capable are you with understanding what is difficult to describe?
