One always has the tow vehicle's 12 volt battery as temporary back up AND tow vehicle electrical system for temporary load support if necessary.

Then that would suffice for a 6v failure also.
Not true, if one of two 6 volt trailer batteries fails one can't load support the remaining 6 volt with a truck's 12 volt electrical system. If one of two 12 volt trailer batteries fails one can load support the remaining 12 volt with a truck's 12 volt electrical system.
Also, for those of us who have limited battery requirements we can choose to run just one 12 volt trailer battery, therefore only have to find a location to fit one battery, and on limited occasions when we might want to briefly power an inverter we can load support that one 12 volt trailer battery with the truck's electrical system, if necessary. Can't do that with a single 6 volt battery.
