Cheap RV Living

I'm dorking around on my computer. I'm re-reading the electricity summary at www.cheaprvliving.com. Click over to that website right now. It's fucking awesome. I'm thinking about the logistics of Truck House electricity. Seems complicated and expensive. Naturally. Gotta get batteries, a battery charger, some way to charge the batteries (generator or some such). Then you have to put wires all over to connect it all, which I'm not super comfortable with. Anyone want to help me out? Oh yeah - gotta be hookin' up an inverter too, so I can have a microwave or some such item. All this makes me wonder if I can live in it more like camping style and do without all that. I don't know, man.
