How and where you drive your coach would determine what tread style to go with. The long-haul are designed for highway miles, the regionals are made with a thicker side wall if you occasionally hit curbs and the traction tires are designed for traction off road. If you've never been stuck I personally would narrow the choice to long-haul and regional.
