The rams are only attached to the outside wall of the slide, right? If not, I don't know what system you have. But because it is only attached to the outside, that's all the adjustment affects.
The only effect it will have to the inside floor is through a lever movement. The floor rides on rollers/teflon pads/something that is on the top, lip, outside edge of the main floor. So you raise the outside, you actually lower the inside slightly. That effect is exagerated when the slide goes further and further in, when the inside of the slide floor is furth from the fulcrum (rollers/pads).
