From what I can tell by searching the sales brochures in our files section,
The Sunspot was introduced in 1978.
By 1982, it appears was the last year the Sunspot was offered in the sales brochures.
I'm not sure how many were made. Sunline Fan is our resident historian guru on the older campers. He may know.
Hope this helps,
