I couldn't find a comprehensive list anywhere that lists all of the various location on our trucks that identify the VIN.
We all know about the obvious locations like the dash, drivers side door jam, glovebox rpo sticker. And I know the factory radio is VIN encoded along with the BCM.
VIN Decoder that is pretty in depth and even tells you how many of your exact truck have been produced with your options.
