From Edmond it is just about as close to travel to northwest Arkansas or southwest Missouri as to the Mt. fork river in southeast OK. The tailwaters below Beaver lake AR has some decent tout fishing and the Roaring river in S.E. MO is fun especially in the winter months. If you want a slightly longer trip (you said you had a motor home) spend a week or two at one of the state parks below Bull Shoales or Norfork dams in north central AR. The fly fishing is excellent in those areas.
