It seems to be marketing, and as an uniformed observer, it appears like the 4.8 exists so that GM can charge "extra" for the 5.3 that most people will choose anyway.
I don't know what I'm talking about here, and am open to being corrected, but I see no other explanation.
The bigger engine always costs more?
The Chevy and GMC dealers in this area will not have an extended cab with a 4.8 on their lots... it will always have the 5.3.
However, in a regular cab, they'll order them with the 4.8.
