The Allure Ultra is more stable than vanilla Allure, but shrinkage is still a potential problem with either vinyl or laminate. And all hard surface flooring has a problem with slides that have rollers or skids on the bottom (just about all flush floor type slides). Most everybody who changes to hard floors ends up having to use some kind of skid barrier when moving slides in or out, e.g. a thin piece of material like a plastic cutting board sheet. We replaced carpet with new carpet for just that reason - our big flush floor slide has 5 rollers that glide over and then rests on the floor surface. Even if it doesn't scratch in motion, it still vibrates as we drive.
