I do not know what the similarities are with the Vanagon pop top mechanism,
but while showing off my '73 campmobile to a friend the "popped" top came
crashing down and hit me on the head like a hammer hitting a nail.  It
scared me and I thought no more of it, until the next morning when I
couldn't get out of bed.  The doctors said that my neck sacrificed muscle
and cartilage to save my bone, and I couldn't have come much closer to a
broken neck.  I spent 2 weeks in bed juiced up on painkillers.
