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...

Your concerns make sense about taxing your alternator, but I never gave it any thought on my previous rig (E350 Born Free MH). That was with 230ah of batteries and the alternator would have about 80 amps draw initially, rapidly decreasing to 30-40 amps in a few minutes. Maybe test the draw on your alternator at a depleted battery level and compare to the alternator capacity? You do have double the battery capacity I had though...
As far as alternator voltage is concerned, the voltage is temperature compensated to a small degree. Hot summer days and/or a warmed engine compartment I only see about 13.6-13.8v and perhaps 14.5v on the coldest days here in Maryland.
