After buying another roll of carpet due to another trashed MH, I’m trying to think outside the box. What about using a paint product as the finished floor surface? It would be easy to clean up, maybe only touch up would be needed, and it would take fewer manhours for make ready. It would need to be heavy duty industrial grade, maybe similar to garage floor paint. You might also have to use a smooth plywood as the subfloor. I know Frank likes to use sheet vinyl for the whole house but this might be a good alternative. Of course this would be for low end homes. The resident could always use throw rugs as needed in certain areas.
