any advantage to changing the 24 volt system to 12 volt on the mc9 or should I leave it like it is |

Advantage:
1) Cheap and easy to use 12 volt mobile products.
2) headlights etc. cheaper.
3) 12 volt RV items more common and should be cheaper.
Disadvantages:
1) Expensive to change wiring to handle twice the current required by 12 volt.
2) All bus components guages, relays, lights, buzzers, etc will need to be replaced (some relays may might work, but you will have to check it out).
3) Cold weather starting will be harder on the battery bank.
4) 24v Inverters use less current, therefore less line losses and more work done. |

I strongly favor keeping it 24. I suggest that you use the money you save by not converting to buy an equalizer and power the few RV items that are available only in 12 volt from the equalized tap on your house battery bank, this almost eliminates Craig's advantages #1 & #3.
I'd add to Craig's list.
Disdvantage:
5. Only half as much power, for charging house battery or powering goodies while driving, from the typical bus alternator (50DN good for 7200 watts on 24 or 3600 on 12)
6. No truly good sine wave inverter available since Trace discontinued the SW 2512.
7. Even when there was an SW2512 the SW4024 offered more continuous power, 4000 watts vs 2500 to power roof airs etc while driving.
