    You have a sticker inside the glove box with your truck's RPO codes. It looks like a bunch of goobildy gook, but each 3 digit code means something and will tell you everything about your truck.

    For a complete list of the GM RPO codes download the PDF at www.moogmedia.com/GM_RPO_Codes.pdf

    Try this one out as well. http://www.compnine.com/vid.php Enter your VIN and it will tell you what RPO codes you have AND tell you what they are.
