Alternator overcharging batteries
I have 4 AGM batteries in my rig with a total capacity of 440AH (actually 880AH @ 6V, but of course they are wired to get 12V). The data sheet for my Haze batteries species a bulk -> absorption cut...

If your two banks of batteries(house and chassis) batteries are charged through a diode isolator there is one scenario that I haves experienced. In my case, the alternator output was determined by the voltage seened at one bank. This method adjusted the alternator output to compensate for any resistive drop in the high current charging line to that battery. It turned out that the chassis battery line had a bad crimp connector in it.The alternator upped the output voltage to compensate, but the house batteries saw this higer voltage and were cooked. This was on my '83 Southwind.
