We traveled the entire length of the BRPW and Skyline Drive with the goal of camping at all the NP campgrounds, we did and loved it. The NP campground site parking pads are short by todays standards, we were in a truck camper so it was a non-issue. During the week the cg's are empty but do fill up for the weekend. Normally we find a site by noon on Friday and stay there until Sunday.
One issue we found was low hanging branches along the drive, especially during or after a rain. We lost a Jack antenna on the rv parking entrance to Maybre (sp?) Mill.
Every few days we dropped off the drive to go into a town for supplies. It was fun visiting little towns we had never even heard of before.
There is a ton of hiking trails if you enjoy that.
Hopefully you will not be rushed and have the time to enjoy it all.
