As someone who works in manufacturing, I do NOT understand how two units could be different. There has to be a CORRECT (engineered) way to do this, and it makes no sense to me why one would be different than the next. I could see things like the wire ties not always in the same place. But when it comes to "mission" critical items like this, I just don't understand how they could be different.

150 amp breaker/fuse/etc should be plenty to protect all 12vdc circuits. Under full load, the reefer when defrosting might pull 4-5 amps on the AC side. This might convert to 60-75amps on the DC side. If we add what might be max for the hydraulic pump which is normally very momentary, I think that it would be highly unlikely to overload a 150amp fuse/breaker. A re-settable breaker might be ideal.
