OK, then the setup I suggested would solve your problem and I think you will find the 80 Amp alternators will be enough with the 3 stage regulator. I would suggest you choke the combine output of the alternators down to 100 Amps to see how it works and then raise it if you think you need more. Maybe installed temp sensors on the alternators and batteries. The regulator is designed to accept these values and slow down charging if the parameters are exceeded.

Another source for the components is Ample Power (Ample Power Company Home Page). They also have a lot of tech bulletin's to make you smarter. I think their prices are a bit higher than Balmar but some people think the Ample Power stuff is higher quality. I've used both and had no problems with either of them.
