Welcome to Airstreaming Nicole!
Yes, you have a bit of a challange but don't get discouraged. I don't know about ozone machined except that fire depts. use them ... something to think about? - call the fire dept and ask them how they work. I can relate to your aromatic dilemma having had the same problem with our cottage, now home, some years ago. We removed everything that couldn't be painted/ sealed or cleaned and put the rest to the curb. That meant upholstered pieces,mattresses & carpet - none of which, in this case, was any good. We have a lot of trees which means dampness. Sunshine eliminates
dampness. Also, try your county home extension office for ideas.
Good Luck Nicole & let us know how thing are going with this,
