Do you think the person that gave it to you would take the time to help you learn how things work? Things like lighting the pilot lights are not terribly difficult, but most do have a trick to them. I would try to find someone in the area who can help you learn some of those basics. Now that you are an owner, you will start noticing the other RV's in your neighborhood, on your commute to work, or at your local WalMart.
Another option, is if you join Good Sam, they have a program called StandBy Sams, to help people in the area. I am sure there are several in your area, one of them might be willing to meet you and go through the basics for set up and break down.
