Beavers Bend in SE Oklahoma is Beautiful... The state park stays very busy and the regular sites are smaller but the park is VERY nice and everyone is friendly. Broken Bow Lake is close by for fishing or you can river fish at the state park. ENJOY
Dangerfield State Park outside of Dangerfield, Tyler State Park off I-20 are great and have some full hookups. Shallowcreek Golf and RV Resort off I-20 just east of Tyler is also nice, expecially if you like to play golf.
