Mine are a dedicated house bank. I have 3 starting batteries for the engines and genset. They were actually cheaper for me because I needed more room in the engine room for more house batteries but in order to get the room I would have had to buy a new self contained A/C system to replace the split system. Now the A/C can stay and I will have a larger house bank along with a new 120 amp alternator for less money than replacing/expanding my old 6 volt bank.
