The Ohio Cruiser model is gone this year, and is replaced fully by the Overlander model name.  The California version sold for $4250 ($4295 Twin).

During the year, the California plant changed over to the more familiar ramp shaped wheel-wells of the '57-'58 era.

1957 also saw the change from 9 end-cap panels and the "whale-tail" to only 7 panel segments in California only, with Ohio lagging behind much later in the year.

 

This example is Ohio made O-7496.
