Even if you have the vents you still run into the "air compression" thing
closing the last door. I think the vents must have either a springy valve
flap thing or maybe a small-cell foam "filter", 'cause they don't let air
out fast enough to keep the door from "bouncing" if you don't shut it hard
enough. I think this is just the way the Type 2's were made. My mother rode
in my Vanagon for the first time recently and had to try twice to get the
passenger door shut. She commented that the 1968 Bus she bought new was
exactly the same. I think it's just the way those Germans made 'em.
