think about it this way, the v8 is bigger, but it will move the truck with less effort. The v6 "should" get better MPG's, but it has to work much harder to move the larger truck then the v8
I have the 4.6 in my truck, and it has plenty of power, and I would never get the v6, because it would limit the abilities of my truck when it comes to hauling or towing. That is not something that I would sacrifice for the possible 1 to 2 mpg that I could save with the v6.
