Any alternator would be capable of charging 3 batteries, it would just be slower with an alternator with a lower output. My Silverado has 2 batteries, and when I'm towing my 5th wheel, it is keeping all of the batteries (truck and camper) charged and powering the inverter in the camper. It has only one 125 amp alternator.
