If you are a dedicated old school kinda guy but you still like mods and upgrades...
When I was running my Pig daily, off road and road tripping it too (took the family on a round trip Alaska Highway jaunt)... I used to run duel alternators with factory mechanical regulators. I am sure I could have converted to a GM one wire and put out almost as much power. But I had this stuff on hand. Plus, by carefully adjusting the contacts in the regulators I could tailor their performance a bit. I set the upper voltage limit to just barely over 15 instead of 14.5. This gave me brighter headlights (remember, old school halogen filiment bulbs, not LEDs) and faster heater fan motors too. One alt was designated as the primary and ran all the time and the secondary did not turn on until the voltage dropped to 13V. When it did, they both pushed power.
The redundancy was a big appeal to me. In fact it came in handy on that Alcan run when the primary died and I just continued on my way, no big deal.
