I have a Yakima on my little Japanese Chevrolet (Nova).  Great rack, I agree 
with the NBA center comment for the Vanagon.  For the rear hatch I would be 
very careful since the Yakima aircraft style mounts are load limited to 
about 100 pounds and are designed for the car top aero-loads.  I venture 
that the shock loads of a good bump reacting through a center of mass 15 to 
20 inches from the hatch might well exceed the continuous aero loads and the 
structural capability of the attachments.  The hatch or its frame might also 
yield.  Better think this one out.

P.S. If it works it would also make a heck of a good ski and general purpose 
rack but...
