Eric, full disclosure, I am a former GS Super Nova owner. Having just traded in my 6372 about a month ago.
I was told twice by two different dealers that "Gulfstream was out of the motorhome, but not towable business", and as such,
suffered a 20% hit on my trade in.
When I checked with the home office, with my contact there, I was told that they were making units to order, but not mass producing coaches just now,
waiting for the market to give them direction.
I was able to get parts for my coach when needed, and got a ladder sent right away when I backed into something and damaged mine.
Think others have commented that their website does not reflect new units available in motorized division.
I have not seen anything one way or the other on RVIA or other news sources as to what the company is thinking as far as product lines.
Do believe that they don't have a lot of International chassis around to build coaches with also.
Hope this answers some questions you have.... sorry I couldn't be more definitive.....
