On river rd there are parking areas for rvs. No.hook ups though. Very small pop ups and the like may make it inside the park but it won't be easy. Big rvs and motorhomes wont make it inside the park. Those would have to stay a long river rd
I know in the Chisos Basin there are generators allowe in a part of the campground
In Big Bend Ranch State Park you can pull any size RV in and around the park. There no hookups but generators are allowed. Very easy for any size RV.
