I think you'll want more than one pair.
60A is what, nominal over 1000W, and in far north conditions, you want 2-3 days' usage only 50% usable so at least three pair, 600+AH

for wiring patterns, #2 is fine.
If you can't get to shore power on demand, may want to get a little genny to make sure the bank gets to 100% (most) each day for longevity. A battery monitor will help.
Run the genny in the morning say 80-85% SoC then let solar finish another 4-5 hours.
