It seems like once it drops to 12.5v and less then it starts acting up

Did you find the cause of your problem or are you still having an issue? Voltage-wise you really shouldn't have an issue cranking until the resting/non-cranking voltage drops below 12.1 or so and even then a resting voltage of about 11.8v or better should still turn it over while only sounding a bit sluggish (assuming you have the same 4 battery setup that my 2012 587 has).

I'm thinking a bad starter.......
