Jack,
Are you implying that you have kept not only your 12V engine battery, but also you have a 12V coach battery?
Maybe I did mine wrong, but when I went to 48V LifePo4 coach batteries I only kept the 12V engine battery to run all 12V loads. I permanently wired my coach 12V systems up to the engine battery by skipping over the merge switches near the isolator.
I kept my 12V inverter as back up if needed. I charge the 12V battery from the 48V battery directly with a smart solar controller that is faked out by getting battery power instead of solar power. I sized it at 50A so I can power any important loads continuously without discharging the engine battery for a quick get away.
