Go to website to see photos of every camp site and the measurement of the driveways. You can park off the driveways for the 2nd vehicle. Trailers are not considered vehicles
You would have to ask the ranger but there was parking by the ranger station. We stayed at the first campsite so it was close. But there are campsites much farther than the ranger station. They do have double campsites that can fit 2 cars or an oversized RV. Sorry I couldn't be more help.
