This wood floor thing really takes a beating. Most RV's all the way up to the million dollar monsters, still have wood subfloors. They are reliable, inexpensive, and easy to work with. Is the new, no rot, no VOC, no glue, materials the way to go? PROBABLY. Airstream's way of adopting these things is slow and I think that is a good thing (most of the time). No changes, only improvements. Sometimes the New-New Thing seems obviously better. Sometimes it turns out to have unintended, disastrous consequences. If these new materials show they can hold up to real world usage, they'll make their way into the Airstream production line.
Earthbound can afford to experiment on its customers. They have no market share, no brand legacy, no loyal customer base, NOTHING TO LOSE. If those trailers start falling apart and the company is crushed by a class action lawsuit, they'll fold, leaving everyone with no warranty, no parts, no dealers. You can bet the principle investors will spring up with the next New-New Thing a year later.
The great thing about an Airstream is that if you want to get out of it and into something else, it'll have a much better resell value than anything else. I actually sold my 2007 25FB CCD for a few grand more than I paid for it just 18 months before (bought it used). We had over 60 nights of great fun and we learned what we wanted different in our next one.
Go to a vintage trailer rally. I've seen hundreds of vintage trailers, and it's not uncommon for one to have an original floor that is 50 years old. And the others are usually rescues and the current owner rebuilt with wood again.
