Hi,
For your upgrade, consider one of the hybrid inverter chargers from Victron, Outback, or Magnum. They all allow charging at over 100 amps.

Finally, now I bought a Champion 3100 generator so I can charge batteries and run AC if I want to. I only use it sparingly, but it definitely extends my camp time. I've given the group 24's to someone who needed them. I'll probably upgrade my charger so I don't have to run the generator very long to bring the batteries up. The generator weighs slightly less than the pair of group 24 batteries.
