Just a note about the Mt. Nebo campground. The road into the campground is restricted to trailers and rv's less than 24 feet. It's full of hairpin turns and switchbacks all the way up. In fact, the info on the Arkansas state park site even suggests you turn off your A/C and use low gear. I've made the climb, sans trailer, and it is worth the visit. However, you may want to make this one a day trip and leave the rv at the bottom.
