I've always wondered the same thing...... I am pretty sure that I was told.... that one alt runs all the time.... and that the second one kicks in when there is a power demand that is more than the first one can handle. Now.... if that is true..... it seems to me that the second one would kick in if the first one wasn't making enough power, such as in a primary failure.
and.... I'm sure you can make your truck a dual alt truck if you wanted too... but it is gonna cost a pretty penny compared to what it would have cost as an option. I'd upgrade to the bigger alt before I would try to get duals in there.
