the commander has a 160 amp alternator. the commanders that came with the 3.7L V6 have a towing option add on that uses this option. i think it would probably bolt right up to your motor as well.
i have the 160 amp alternator and a yellow top on my commander with a V8. i never have charging problems. the winch doesn't slow down any when its operating as well. its a good combo. i may add another battery with an inverter later on.
