I see even less advantage then. As I said, a remote sensing setup gives you far more accurate battery voltage when set up, and the heavier the loads are on the system, the worse a one-wire is for this. Needing/ having a larger amperage alternator changes nothing about the regulator or wiring.
I used to run the big frame (120A?) Chrysler alternator on my old Landcruiser, with two batteries and a winch, and used the very same old 70/ later Mopar regulator. I used no6 charging wire and a 100A SW ammeter. It would peg that ammeter when using the winch, and never hurt a thing. In fact, that same old regulator still works, although it looks "like hell." It went on that Landcruiser in 1975, and I recently pretty much junked the old girl out.
I fully understand that LOTS of people use 'em but I just find no advantage to them.
