There's a Honey Creek State park in Grove, OK that we've stayed at, room for big rigs, elec & water at your site with a dump onsite. We stayed at Natural Falls several years ago and it was nice. If you will be traveling I 49 there are 2 Corps of Engineer parks that are about 7 miles east of I 49, closer than either of those OK state parks. You didn't say when you were traveling but both have sites open year round, Prairie Creek and Horseshoe Bend, both in Rogers, AR. Both have big rig access, elec & water at site and dump onsite. Prairie Creek is off Highway 62 to 2nd St, then Hwy 12 to the park, Horseshoe Bend if off Hwy 94. You should check if Devils Den can accommodate a bigger rig, if you have one. There is also a private park in Cave Springs, AR, look at www.rvparkreviews.com for the name, it's pricey but not far off I 49
