Welcome to iRV2! I used to own a KIT Sunchaser. I am pretty sure the company is no longer in business. Your best approach is to NOT remove the slide, but try to replace it from inside. I realize it will be more difficult, but by removing the existing floor and replacing with new material, I suggest cutting the new material in half to facilitate easier installation. Another approach could be to put new flooring on top of the old and using a combination of glue and drywall screws to draw the old material up to the new. Perhaps, by running the slide to the out position and using some jacks to raise the old floor slightly would help facilitate this 2nd approach. Best of luck!
