I've been in love with the trailer for years too! This is a 1972 AS. It was designed by Toronto firm, Powell and Bonnell. They refurbished it for the 2000 Interior Design Show in Toronto so that they wouldn't have to tear down their exhibit at the end of the show. I have no idea where the trailer is now. I think it was supposed to be auctioned off at the end of the show. I'd love to see it in person!
There were several articles published about it in Canadian decorating magazines like "Canadian House and Home" and "Style at Home".
