Wire gauge recommendation
To get the most efficent charging to my batteries, with cost kept in mind, what wire gauge should I use between the batteries and charger? I have a pair of 6v gc batteries. They're about 12-15 fee...

I am not sure who recommended 75 amps for two batteries or a Boondocker for charging on generator.
Bigger wire will make a measured improvement. Trouble is the Boondocker will drop to normal mode 15 minutes after the voltage at the converter reaches 14.6 volts. This might be 14.0 volts at the battery, maybe less. In effect boost goes to about 70% charged. This might seem odd but the 35 amp would have been better because it would have boosted into a higher state of charge. Fine for utility power and lots of time, not so much on generator. And yes still better than WFCO.
Give it a test but if Randy would trade it for a 9260 or IOTA-DLS-45 I think you would be better off. The #6 is fine if the converter holds boost mode.
75 amps available will not hurt the battery one bit as the voltage is well within the recommended limit.
