My wife and I took a big trip last fall to all the states in the map in my sig below. One of our favorite stops was outside Theodore Roosevelt National Park. We have a big 5er (45') and sometimes have trouble finding suitable spaces, but we loved the little county park outside the NP. It was one of the prettiest places we stayed and it only cost $6 for the night.
Buffalo Gap CampgroundThere's a lot to see in the area, but fuel up before you get there. We had to drive most of the way to the Montana border to fuel up the night before we left.
In addition to visiting the Roosevelt park, we also spent a good part of a day driving the Custer Trail. It's mostly gravel/dirt roads through the countryside and oil land. There are some gorgeous stops along the way though. At the western end of the trail before we made it back to the highway, we stopped at a little municipal golf course and hit a couple buckets of balls as the sun went down. They couldn't have treated us more nicely, even though we only spent about ten bucks on the balls.
From there we drove down to Hill City, SD, which was a gorgeous drive.
The people, the land, and the sights were amazing.
That whole area is heavenly, at least during the part of the year when they don't have snow.
