Toll on the Kansas Turnpike from the OK-KS state line to Wichita towing a double axle fifth wheel in August was $4.20. Fortunately my TXTag (Tex-tag) was good in the express lanes.
We mimicked your return trip since we were going to Custer from the Houston area. I-35 to Wichita, I-135 to Salina, I-70 to Hays, KS, US-183 north to I-80, NB-71 to Scottsbluff area, US-26 to Lingle, WY, US-18 into SD & the Black Hills area.
