Your RV electrical system is really made up of two systems: There's the main 12 Volt DC system, which runs the electrical system for your engine, and there's the 120 Volt AC system that powers your appliances and other electrical components inside your RV. To change the 12V system into 120V, you need to use electrical hookups at a campground, an inverter, or a generator. All of these are readily available; you just have to choose the option that's right for you and the way you camp.
Remember, all campsites don't offer electrical hookups. Generators can be noisy, and they can give off quite a bit of exhaust. Inverters can be costly, but if you choose an inverter/charger system, it can help keep your 12V batteries charged, so you don't run out of power options when you use your inverter. There are many different choices when it comes to powering your RV electrical system. Once you camp a few times, you'll be able to see which RV electrical system makes the most sense for you.
