This is going to sound dumb, but I can not locate the LTZ model on Chevy's website. Where is it? They have the LS, LT, and North Face editions listed. In the LT options, there is a #2 package that sounds similar to the LTZ, but I'm not sure

They did away with the LTZ model for the 2004 model year. The LTZ is basically the same as the 2004 LT with the 1Se (or something like that) package.
