Connecting a second 12VDC battery
How is the second battery electrically connected? Just paralleled? Do you add a disconnect for each for quicker charging one at a time? Thinking another battery would be better for boondocking.

Use the diagram shown above. Note that you get more than twice the time at the same amps draw by having that second battery used together. So don't use them one at a time. (Peukert works for you!)
Charging them both back at once takes no longer, and even might help if you have one of those WFCOs that has a hard time getting to 14.4 instead of staying at 13.6. (Doing two lowers your charging rate for the same amps perhaps letting it see the 13.2 trigger)
