My Dad had one when I was a kid. It was a 3/4 ton. That was how I developed a liking for 73-87 Chevy pickups.
I saw one in a junkyard over the weekend, and occasionally see a red 3/4 ton around my neighborhood. It was for sale several years ago, and I wanted it, but had no space time or money for another project.
I see 2WD Blazers regularly, but not frequently. A friend just picked one up a few weeks ago.
