I live in Kansas and have driven that route as far as Dalhart, TX. I can tell you from that point on to Wichita it's not to bad. Bunches of open prairie and farmland. Plenty of small towns with fuel stations if that's what you are worried about. Also that route will take you right through Greensburg, KS. Very interesting town to see how they have rebuilt everything after the tornado a few years ago.
