Looks like the receiver is pretty mucked up.  Gasket appears stretched and maybe broken, and there appears to be rust or some other dirty looking material on the receiver.  Maybe cleaning it would make a cap fit better, but perhaps it needs replaced.  Or maybe I don't know what I'm talking about.  I've never known of one needing replacing, on a Vanagon or any other vehicle.
