Formaldehyde concentrations in the air in homes has been measured from: 0.10 to 3.7 parts per million. As an earlier poster mentions, the RVIA has set standards for their members to abide by if they want to attain certification (this included formaldehyde-containing building materials use).
I've yet to see ANY truck camper manufacturer provide a scientific measurement of formaldehyde levels in their various models (ppm formaldehyde); so, the use of the term: low formaldehyde levels in campers, etc, etc, are only a nominal value. So, do your due diligence, is all :B
