Hey guys! My name is Derrick, I just retired from the US Navy after 20yrs service and now living in Gulfport Ms and i'm new to this forum. I joined because I'm a do it yourself type guy and the forums are the best place for information. I recently purchased a 2008 GMC Sierra Denali and i plan on a few upgrades. So I'm sure I'll be chating with a few of you!
