Regarding the plastic flooring layers that took the place of luan, our 2020 Cougar 26RBSWE was made in 10/2019. We have the darco covered luan. I don't know when Keystone began using the new plastic.
Yeah I call it cardboard. It's actually luan type of material that has outer cardboard layers with wood in the middle. It's like you took a piece of luan and then applied a thin layer of shoebox cardboard to the outside surfaces. The unfortunate thing is the cardboard layer (since it's on the outside surface) is what is glued to the styrofoam and frame members to make the floor sandwich. When water hits that cardboard, it just disintegrates and delaminates while also acting as a sponge. Imagine leaving a shoebox or cereal box outside in the rain. That's what happens to it. The "cardboard" floor is what it is and it would be mostly fine except that it has zero tolerance for getting wet.
I don't know when they switched to the new floor. I seem to recall reading that it was mid 2020 model year.
