My opinion on this trailer relies on the testimony of many French speaking owners participating to French speaking forums based in Quebec. It is a fact that Bonair had many problems with the Oxygen
which is understandable as this was their first integral FG trailer and a totally new model and concept. This is not surprising at all.
The introduction of a new model is also frequently a killer. This is exactly what happened to Trillium
when they introduced the very limited edition of the 5500 (somewhere between 65-85 units). Even if they were very experienced with integral FG trailer (they were producing the 1300 and 45000) and if the 5500 was not a problematic product, this was also their last nail in the coffin. Trillium
also introduced this new model when they were in a difficult financial sitution.
i don't know Bonair's owner and also don't know if the administration was also falling apart but a company rarely closes its doors when they are making money and are in a good financial situation. Those companies are normally sold to someone else. You don't get into a bankruptcy and close doors when everything goes well...
As far as the selling prices around 10,000$ look at this one :
2002 17ft Bonair Oxygen - Only 1600lbs
As I mentioned most of them are advertised near 10,000$ whatever is the price paid by the original owner and what money he putted in it. This is more in line with the price of 10 years old FGRV. As a reminder a brand new and superb Escape
(19 feet) sells for 24,000 CDN$.
