There was a web page made about a couple that went on a trip in a vanagon
and had a horrible time.  It was written to be sort of humorous.  Stories
about the various trials the Vanagon put them through.  Finally the trip
ended when they rolled the van coming down a mountain road in the
snow.  There were some nice after pictures of the rolled van.  The roof was
completely caved in, in the front, especially on the passenger side.  It
was quite puzzling because the door frame was still mostly in it's original
shape, all the way around the window.  I looked back through the photos,
and saw that they were carrying a big cargo box of some sort in the luggage
rack.  When the van rolled, this was pushed down into the passenger
area.  Something to consider when you decide what to carry up there.
