I recently had my hands on several different brands of used shocks. It
wasn't hard to feel the failure mode or wear. e.g. in the same brand
and vintage shocks, the difference in feel by hand in failed low mile
near new vs new, was obvious even to this untrained DIY type.

I'd suggest that there's a lot of Vanagons out there running on the
original springs. Sagging (too short) springs would most likely aid in
damaging new shocks.
