We leave ours on, Tom, and then we put down a piece of no slip material on top of the covers. That allows us to store small plastic baskets full of lightweight things while going down the road. We are mindful of what is in the basket in case of emergency braking that might through stuff around a bit. When we get where we are going and deploy the slide, we then move the stored stuff to another area (often behind the driver's seat or on the carpeted area exposed in front of the refrig with the slide out) and then have use of the sink and stove area. When camped, we just stow the covers in the allocated slot behind the stove. The covers are nice but they are pretty heavy.
