My best friend and I are planning to go on a road trip next summer. It's going to be a month-long, and I imagine it'll be closer to 10,000 miles. (We're driving to maine and then down through the southern states back to where we are) We think around 7000$ will be enough for everything, since we have a small car, and we're willing to stay at really crappy motels. But I'm not sure 7000$ will cover 10,000 miles worth of gas, and food for us, and motel rooms.
I realize I'm not giving very much information, but that's all the info we have at the moment. Right now we just want to earn up enough money to get through.
