This is just what I was told from the guy we bought it from. The owner is sled operator in eastern Tennessee, He said he was good friends with Gary Cook and had so interesting story's to tell. He said that the No Problem frame and body are setting beside Gary Cooks Shop, which you diehards may have already known.
I doubt the truck was ever a stretched wheelbase truck, so it must have been a super modified after they went back to a normal wheelbase? Who knows.
