Dornier Flugzeugwerke
During the mid-1960s, Dornier Flugzeugwerke and Hymer developed the Dornier Delta II, a development of the earlier Zündapp Janus. The vehicle could carry up to six passengers and offered two sleeping places for camping, but was never developed beyond the prototype stage. However, from 1971, serial production of motorcaravans started under the Hymer brand.
