I was always under the impression that running on both batteries would fry the alternator. My Baja has a pair of batteries (single engine) with a battery switch (labeled Off-1-2-Both) and I want to say the switch has a note on it indicating running on both would be bad. I'll have to look once I get it out of storage to be sure.
In my situation, to be safe, I've always run on one battery for an entire day and the next day I go out, I use the other battery and I just keep switching back and forth like that. Since it's parked on the trailer, I don't have to worry about the bilge pump running batteries down.
