Those are all good things to be rid of, but what benefit do you get from tall trucks? Other than that "manly" look?
Weight. A fully boxed frame allows you to reduce weight since the strength comes from the box design and exotic metals rather than the more frame material on a C-channel frame. Essentially it is the same strength of a C channel but much lighter which needs to happen with the upcoming CAFE fuel economy requirements coming to the HD trucks.
