MPG difference between late generation 3.5 and the equivalent 4th generation trucks?

So, say I had two trucks:

1. Stock 2009 2500 QC SB Auto 3.42 Unloaded
2. Stock 2010/11/12 2500 QC SB Auto 3.42 Unloaded

Which would get better fuel economy (if any), assuming both are driven lightly like grandpa? What MPG's should I expect?

Thanks in advance!

You guys know what I mean. I'm talking about the cab that is in between the 2 door Regular cab and the Mega Cab.

So, you guys think they will get about the same MPG's, huh? I didn't know if they improved the aerodynamics substantially, changed the weight greatly, or any other MPG relevant changes to these trucks, so I wanted to check with you all here.
