First of all let me say, I mean no disrespect by this question...
What is the obsession with a half cab for a Blazer?
It essentially converts it to a single cab pickup and leaves the entire rear area exposed to the elements.
Also it's ironic that Greenback TN was mentioned....I live about 6 miles from there. The entire town is all of 2 blocks long...but...they do have a post office...
