Question about differential options

One of the options on the option sheet for my truck is code "G80 - Locking Differential". Exactly what kind of locking differentials did GM put in the trucks? Is it a straight positive traction or is it some type of limited slip? Just curious. I just picked this truck up. It has 2.73 gears in it with supposedly a locking differential, and a 700R4 tranny. I would have thought that with the 700R4 it would have had a lower geared differential. I got great gas miledge coming home with it. I wonder why?
