Charging a Battery Bank
I am planning on upgrading my batteries to 4 6v batteries wired in series and parallel to have a 12v system with plenty of Amp Hours. There is a ton of information on how to wire things up but nothing...

There was mention of not using the converter/charger that comes with campers as a way to bulk charge the batteries because of how far away they are in most circumstances. In my case, I estimate 28'-30'. Is that because of the normal 6 gauge wire not being able to handle high amp output (over 55-60amps) and the loss of charge running that length?
The wire can handle the 60 amps ok. It is the loss of voltage--wires too long, high R. Even with fat wire, that is too far, so changing the wire won't help. Voltage seen at the battery is lower, so not as much over the battery's voltage, so less current to recharge with.
It is ok there as a converter, or to charge the battery on shore power where time doesn't matter. Fast charging is all about generator time reduction.
