Dual alternator setup?

[Rawze]

Back in the 80's people used to put 6 or 8 or even sometimes 10+ alternators of 250-350-amps or more on their trucks for big-power CB and ham radio amplifiers. -- people used to do it all the time. They also used to run 6-volt + 8-volt farm-tractor batteries in series combinations to to get the voltage up to 15.5 volts for extra power handling too. It was not so unusual to see a truck with 25,000 or even as much as 40,000 watts RF power transmitters in them back then with all custom built components.

It is just a matter of finding the room, making the brackets, getting belts, adding wiring, etc.
