Just ran across this and I remember your search years ago. I really hope all this works out for you.
Sometimes in this hobby you run across people that "act" as though a vehicle is really special, only to horse trade or sell it away because they found something else more special. It's pretty well apparent how important that truck is to you; you stayed persistent for years, found it, and upped your offer to get it.
I wish you all the best in eventually getting it.
