Dirt
Previous 3 travel trailers all had wall-to-wall carpet. Thought we were doing a good job keeping them vacuumed all the time. We now have a 5er with no carpeting, except the small amount in slide outs....

This is why it's recommended that folks with allergies, asthmas, etc., eliminate carpeting in their homes. Not only does carpeting retain dirt and such, it also creates a film of disintegrated backing that gets wafted through the air.
