Try the McClellan Creek National Grassland off I-40, about 20 miles west of the OK line. There are RV hookups, a nice lake bordered by shade trees, miles of grassland around, and not much else. It's about 3 miles off the interstate at it's own dedicated exit. About 10 miles east of the park is McClellan, Tx. The Red River Steakhouse is there. Good food for reasonable prices.
Enjoy your trip.
