maybe with the new chevy HDs coming out you can get a great deal on a 2014, only thing is the interior that you wanted a little change from. im a chevy guy only other truck I have owned is a Toyota when I was 16.
is your avalanche a LTZ model? I went from a LT 1500 Silverado to a LTZ 2500 Silverado and the interior was much nicer. close to the same layout but I like it. the new chevys are nice, I hated them in pictures but went and looked at them while my truck was getting service and they are really nice looking, the price tag on the 1500 was a little crazy for me.
