Lucy actually has 3 electrical systems: The cab of the truck section has a 12 volt DC system, a 12-volt DC system in the coach section (the living area) and a 120 volt AC system in the coach.
The truck cab section gets it's electricity from the truck battery, 12 volts that runs all the outside truck lights, the truck interior light, windshield wipers, cab air conditioner, etc. and the radio, camera system, the cigarette lighter. We will have a gps running from the cigarette lighter. Basically all the same as regular truck.
The Motorhome Coach has a 120 volt AC system. The air conditioner, microwave, refrigerator (it also runs on propane), and all the 120 plugs use this system. The 120 is powered two ways:
1) Shore power (external 120v power system like plugged into a home or rv park).
2) Generator - Lucy has an on-board generator that generates 120v. The generator is somewhat noisy but necessary for that refrigerator and roof air conditioner.
The Motorhome Coach also has a 12 volt DC system. This system is powered by a deep cycle battery. It is kept topped off by an inverter in the front of the cab and a solar panel on Lucy's roof. Some motorhomes have lots of deep cycle batteries so they can "boondock" or live without shore power and city water faucets for a long time.
We are going to have to get used to keeping tabs on the power we are using both the 120 and 12 volt!
