I see the truck manufacturers all have an optional dual alternator package available. From the point of view of a tow vehicle pulling a TT, is this desirable? What are the benefits here?
As far as I can tell with dual alternators if one fails you can run on the other one. So it seems to be for vehicles that must keep going, emergency services for example. I just got the heavy duty alternator.
I just looked online and it seems as tho these are for very heavy loads, once again emergency vehicles running lots of aux loads like those strobe lights or tow trucks that need the extra power to run various equip.
