Congrats on the order!

Mine is a '12 short bed and it does have the 35gal tank

Sounds like a really nice truck you got.....I feel I really got lucky with mine.

I went to test drive a 6.2 last Saturday and they had 2 '12's left one was the truck I got and the other was a black one with a few less options. The only thing my truck did not have was a sunroof and Nav. I almost pulled back and thought I want a fully loaded truck but it really didnt matter. I had a sunroof in my Denali and honestly did not use it that much. And as far as nav its nice but the nav on my iphone works pretty damn good. Besides I fell inlove with the White platinum color and they knocked the price down to $41k the sticker was $48,600 I know they wanted to move it and make room for the '13's

Either way I am tickled to death with this truck......you will love it!
