I surprised no one has mentioned the stock "Spoiler" for the Type 2 (aka
Vanagon) Campmobil that was installed instead of the traditional "Luggage
pan" but not imported to the US.  There have been several pictures around
the internet but I can't seem to find any now.  You can, however, find a
diagram in the ETKA software.  Look at "Local Market >
Campmob.(Typ2/Trans./LT) > 1980 A > Campmobil-Typ 2 > Extras > Spoiler .

This also suggests the official usage of the term "Campmobil".

In the same area you can also find the interesting Campmobil-LT that is
listed from 1983 to 1996.
