I have the set up that you describe with all AGM batteries. Number 1
(group 24 I think) is starter and number 2 (4D equivalents) are combined
two batteries for house. I have only used starter battery ocassionally.
You can isolate and use as you described and switch with out problem. When
on shore power I leave on both as it charges. Never had a problem. This
set up allows me to use fridge, lights, stereo at anchor and still have
starting power by only using house battery selection for power at anchor.
I do not have wind or solar backup and a weekend at Cape Lookout has not
been a problem. Motoring in ICW or NC coast area keeps battery topped off
in between anchorages.
