Carpet vs laminate or planking

Have someone activate each slide while you observe/measure the carpet to bottom of the slide for adequate clearance. If any drag across the carpet close enough to the subfloor, you'll likely drag across any vinyl or plank flooring.

The advantages to vinyl plank flooring is it's easy to put down, much easier to replace when damaged, lower profile, and it's cleaner than carpet.

We have vinyl floor with throw rugs ... works great, easy to keep clean. We have no slides.

At one time, they were pushing carpet because the slide...slid across it and would tear up the vinyl over time. I think the newer ones no longer do that but might want to verify.

The trade off is you will see the dirt with vinyl but you can clean it. Reality is once the crud is down in carpet...it's there forever. I know lots of people with stains on the carpet that are never coming out.

Cold floors are easily addressed with some throw rugs.

Our preference is vinyl flooring (the planks would be fine so long as they don't interfere with the slide out).

I would go with thin vinyl flooring rather than heavy planting type materials. If you camp in the colder months, the floor will be cold. I put indoor/outdoor carpeting on top of my vinyl flooring. I can remove the entire piece for cleaning, including scrubbing and rinsing off with a hose if needed. I only did that once but have pulled it out for shaking/beating several times.

Washable throw rugs can “carpet” any area you choose.

Vinyl plank works well and is ready to install.
