I started looking at a 07 and 08. Talked to the dealer yesterday and he told me with incentives I could get a new 09 crew cab 4X4 for $38-40k. He also has a 2010 crew cab 4X4 silver dually on the lot that is $52500 out the door with 1.9% financing for 60 months (a 15k difference). So the question is which is a better truck?
