I agree.  The 50/50 mix is dictated by the varying conditions that Vanagons
will see.  Anti-Freeze by itelf is a lousy thermal conductor.  If cooling
efficiency is your goal, run straight H2O (theoretically, corrosion
resistance not considered!).  If you're in a cold climate move the mix
toward more anti-freeze since you're not worried about cooling efficiency.
