I am picking up my new truck on Friday.
I wound up going with a 2007 Chevy 3500 Silverado for a few reasons. The biggest one was the Allison 6 speed transmission. I had a 2004 Ford F350 & started feeling a slipping and hesitation in the tranny.
One of the other reasons was after a lot of surfin for information I found many good articles like this one from Edmunds, this was a head to head test on 2006 trucks.

I will also say that the Chevy is MUCH quieter than either the Ford or Dodge.
I will miss my King Ranch though it had a lot more style and was better looking. Ford also offers tow command & the tow boss package. The 2007.5 Chevys I think look like a Ford, they will be out in March/April.
Also the Ford offers a 4.30 ratio rear and a 4.88 rear to get to those 24,000 lb numbers. Do I need 24,000lbs? I might be wrong on this but I have read that the rears make a big difference in fuel economy.
The new Chevys come with a 6 year 100,000 mile warranty.
