Not sure I can describe this but......We have a 2011 greystone 29mk. When drivers side slide is in the floor of the slide tilts up about 3" on the front tapering back to laying flat after about 3 Ft. It fits flat on the floor for the entire length after this. Looks pretty odd. Not sure if its a problem. Scared to step on it because the floor may pull away from the wall. Any thoughts on this? Thanks ...Al
