Er...not sure what this has to do with Vgons -- the Vanagon flue cap covers
the exposed end of the otherwise-sealed refrigerator burner-air system
(which exits through the driver-side wall amidships).  This "vent" provides
both intake and exhaust air for the burner.  Any water produced or
introduced into the system drains down into the burner chamber where it
(potentially) floods the burner.  There is a drain extending to the
bottom-front of the reefer whereby such water may be drawn off -- but you
really don't want to squirt your car-wash hose in there, hence the
cap.  Some folks drive with the cap in place, but it is not UV-resistant
and deteriorates in those conditions.
