Cavco manufactured homes
Purchased 6 yr. old Cavco park model .Moved in and had terrible ''dust problem''. investigated and discovered heating ducts were not connected to floor and '' dust '' was fiberglass!
After I moved in to my Cavco home I found out the ever present recurring ''dust ''was actually fiber glass insulation being blown in by the furnace . Only one of the floor heating ducts had a connection to the main heating duct .The remaining floor vents were just blowing into the crawl space,stirring up the fiberglass insulation and then circulating into the house! ( No wonder the kitchen floor was so warm if the furnace was on.) The 80 year old lady that i purchased this Cavco home from was breathing this ''dust'' for six years! I thought she was just a poor housekeeper because the frige coils were so impacted with ''dust'' it was like a solid sheet , as was the bathroom fan. There were other minor defects that i could address myself but they weren't hidden dangers to my health .
