as far as I know it would make sense to discontinue these as the fridge vent
is directly under the open window.. but as I am making a weekender that is
not such a problem..
  Also VW was looking for a more modern looking van for eastern europe and
the states where fashion defeats function.. probably why the still use the
loaf down in south america.
the modern look was also the main reason for the square headlights IMHO  to
get outta the "dated" rut the Hippie vans were in for decades and still are
referred to.
 and IMHO it wouldn't be anyway just use appliances that burn with care and
know the issues/symptoms and causes   always use adequate ventilation.. now
westfalia werks couldn't use that warning for the "masses" as there is
always the clueless majority that'll hurt themselves on a kitchen knife and
look for someone else to blame. and that is why we have lawyers.
 to protect us from the clueless people's lawyers  :)
