While my service manager was talking to me about the SRTTE last fall he mentioned that he was a member of Chargerforums.com. Out of curiosity I looked at the site and saw a post much like yours. It seems Chargerforums has (or at least had) a member who was able to determine by VIN if a vehicle was used in the SRTTE.

Kind of a long shot but you may want to post your question on Chargerforums. The site members like the Crossfire so you shouldn't have any problems getting help.
