What's the recommended engine battery?

I live in NorCal, weather is warm, mid 30s at worst in the winter.

Workhorse chassis, 8.1L Chevrolet powered. 35-U

Workhorse recommends a size 78 battery with a minimum rating of 690 CCA.  Since you say it never needs to start at temps below 30F., an MCA rating of 690 should be adequate.  The difference between CCA and MCA is the temperature at which the cranking amps are rated.
