Another reason for the high pop top is aerodynamics.

The Westy arrangement is almost the worst possible aerodynamics on a
Vanagon. The luggage carrier adds to turbulence and the higher angle of
the luggage carrier adds to the frontage area of the windshield.

Other hightops have less turbulence, because they took a more raked
line from the top of the windshield (as these high pop-tops do too.)
