My FIL had one, it was an early 2000's model, and by 2009 when he got rid of it, it was downright dangerous to drive with the typical GM Astro van afflictions; sloppy rag-joint (lots of play in the steering), super bouncy dead shocks, and a failed ABS module that caused it to activate unexpectedly. I remember borrowing it to pickup a fancy new flat screen TV (it was 2008/9ish) instead of putting it in the bed of my Sonoma and immediately regretted the decision.
Aside from those issues, which are easily remedied with a bit of basic maintenance and repair, they did run forever, and were very versatile.
