F85 Sport Crew
 

Hello
I just purchased an 06 GMC 4door F85 Sport Crew. This truck has the 4.8 small V8 and 20" billet wheels. Can anyone out there tell me if this F85 package is something my dealer is doing or is this some cool factory option.? Looks like a small lift kit has been installed along with the 20 wheels. The window sticker indicates a towing package as well. Anyone have any information ? about this package.

Thanks
Mark
