I recently purchased a 2004 Sierra 2500HD. I am ecstatic, absolutely love it. Especially, since I'm 6'7" and have been driving around in an extended cab Sonoma for the past 8 years. My wife has a 2005 Yukon which of course I drive all the time, but it's just not the same as having your own truck. I am a Surgery Attendant at a hospital in Sacramento, CA. I hope to learn as much as possible about my new truck starting with performance and durability.
