If you're not looking at dSLRs, it's probably not going to work very well. I brought four batteries for my old Canon 5D Mk III, and used three of them. Keep the batteries close to your body to keep them warm. Do not change lenses getting in and out of the vehicle, or you'll be dealing with condensation issues.

As for camera choice, the fastest wide angle lenses with the largest sensor camera will help. Don't forget you can rent lenses if you don't own something appropriate. But whatever you choose, don't forget to look up and enjoy the view, too! Good luck!
