Figured it out.

Welcome to San Francisco. At night it gets really wet and foggy. Seems the
condensation was collecting on the top of the van and running down the
rainguards into the back of the van.  It then pools up and drips out.  I
wake up late enough, usually, to miss the condensation part and only saw
the leak.  This is why it was leaking a slow drop 10-15+ hours since I
parked it and not leaking several hours before and/or after that.  I went
back and looked at it last night and there was no leak. I looked this
morning early and saw the leak as well as water literally running through
the raingutter and into the sidevent.

Coolant level is the as when I parked it. It can't be anything but
condensation - esp to have not be leaking Sunday at 8pm, leaked Monday am
at 8am, no leak Monday at 10pm and be leaking at Tuesday at 7am while the
van is covered in water and has a trickle from the gutter into the vents.
