Not that my thoughts mean a hill of beans!!
But, isn't formaldehyde present in carpet, whether it is in your home on wheels or your stickbuilt home?? And, in a lot of other building materials that are used in more than our rolling houses??
Isn't this a health situation like "lead" in paint, etc?? It should be addressed in wider terms than just RVs??
Sorry, might be a bit off topic here.
