VW lowered the later vans for some reason/reasons. Personally lifting a van for off road clearance is silly and can even be dangerous. Most lifts are done by just using taller springs, adding shims etc. One design consideration is suspension drop. As tires need to fall into pot holes, ruts, etc. the suspension has to allow the wheel to drop. If not enough drop room is there the vehicle has to then dip on the corner. Same goes for a flat tire, blow out, tread separation or even a wheel falling off. Upset the vehicle enough at speed and hold on tight as it rolls over. And I have seen my share of Vanagons that have made it on its side so I know it happens.
