I would say that's the best Q&D way to do it. I've not made the calculations:

Take current draw in amps of all 12v accessories connected to the 12v Auxillary battery.

Divide the AMP HOUR rating of the brattery by the total current draw in amps. That will give the number of hours of operation in the 12v battery before recharge is necessary.

Mite need to subtract about 30% from final calculation becuase no battery can be used to the last amp.
