Will be suitable for me to layout an earthen floor/cob floor in a van ?

hi! ( this is my first post, so i'm still getting the hang of things)
I dwell in a small-ish van. currently, carpet lays on top of the metal base of the van's body. I would like to remove the carpet and lay out something else...anything but carpet, traditional tile, laminate/vinyl, or hardwood.....I am interested in laying a cob/earthen floor in the van but I am unsure if this is unattainable. I would be able to let it adequately air-out for as long as need be. what do you think about this? is this a sensible option?

I am open to suggestions, even ones unrelated to earthen floors......does anyone have experience with "installing" paper-flooring? i've read that people have laid paper on floors inside of homes and then sealed the surface of the paper...I am wondering if this is an option ? any advice, suggestions, tips/tricks would be greatly appreciated!! thanks in advance...peace... -wande

It will work fine, as long as you never drive it. I can't see it lasting very long if you do, unless you make it thick enough your tires and springs die first.

Lots of people use plywood or pre-fab wood flooring in RV vans, it should work with "less processed" wood as well. Reclaimed pallet wood would make an interesting floor.

The problem with van floors is they are terribly uneven, corrugated for strength. The earthen floor would solve that, paper wouldn't. Most paper floors are made using non-toxic wood glue or basic elmer's--neither of which grip to metal or paint well.

Could try a papercrete floor. Lighter than cob, put it in as a thick slurry and screed flat... But I don't understand the point of the exercise to begin with?
