Can't speak to your particular RV but I did recently have the carpet in a Winnebago motorhome removed and replaced with Allure vinyl. They moved the slide-out to a mid position, tilted it outward at the top, and removed the screws holding a metal strip under the leading edge of the slide floor which held the carpet. You might try that.
