06 isn't an option on the site :ninja:

I've tried to do the same thing. Try cars.com. You have to search for it, but they do have the 2006s up. They've actually had it since early July. I don't know why Chevy and GMC still have 2005 on build it, considering they aren't building them anymore!

GM probably wants to sell off any 2005s that are sitting on the lots, not have them cannibalized by 06 sales.

I do not believe that detailed prices for the 2006 full-size trucks have been released to the public.
