I haven't heard anything about FG production stoppage.
I bought my first FG in 1993 and was also told that the FG was no longer being imported to the US. And indeed importation stopped until 1998.
I purchased the last available 1993 FG in the US. I had to fly / drive 2400 miles to get it.
But it never affected my ability to get service, parts or warranty work and we drove the resulting custom expedition camper all over the US and Canada.
When they started importing again we converted the 1993 FG to a stake truck, purchased a new 2004 FG and built a new expedition camper.
They are great vehicles, at least our 1993 and 2004 have been, and I wouldn't push back because of "dealer talk" about excess inventory.
Sounds like an opportunity for a deep discount.
