There were no model nameplates during this era, so sometimes you will see these 22 foot trailers also mistakenly called Safari (O-6434+) or Caravanner (O-9100+)

California's only 22' trailer in 1957 was the Flying Cloud, and it sold for $3995 ($3650 Twin)

1957 was the last year for many things: the California whale tail, 13 panel end caps (mid-year), Hehr "Standard" windows in front and back and the Bargman "9" recessed taillights.

Ohio bathrooms are on the curbside, California on the streetside.

To the left is a nicely renovated Ohio FlyingCloud.
