You might try Home Depot or Lowes and ask someone in the lumber department.
I'm sure there are synthetics and composites made to look like wood, similar to laminate
flooring. Depends a lot on how picky you are about real versus synthetic materials in
appearance. In fact, maybe some sort of sheet flooring might work.
Anyway, I'd start with a hardware or home reno type store.
After all, it is a "home on wheels", isn't it?
