Hello to all!

I'm a newbie and just purchased a 2001 Blazer 4x4 4dr with TrailBlazer trim having 30800 miles. I'd most sincerely appreciate any info/help that would make my ownership of this truck more enjoyable (my only other Chevy was a 1970 Malibu) - I'm not used to 4x4 systems that you don't have to go outside and lock the hubs on :) If anyone has any suggestions or tips on this vehicle sent them along; I'd be most grateful. Thanks for the opportunity - I'm glad to be here.
Russell
