We stayed in Chisos Basin for two nights in our Airstream Basecamp 20x and had a great time (for anyone worried about the drive, you'll need to be careful but we found it doable). We knew before we booked that the spots would be tight and we'd be close to our neighbors, but that didn't stop us from having a great time. The bathrooms were clean and the campground hosts were friendly, and we loved that the trailhead for the Window Trail was right in the campground. Probably not our favorite Texas campground (that would probably be in Caprock Canyons State Park) but definitely plan on visiting again in the future.
