Jeff, I have made it to Rapid city in under 6 hours and thats past where this is. I bought my Jayco up there for 3 thousand cheaper new than anywhere else, drove up and back in the same day. Even came back through the black hills so I could see Mt Rushmore.
Note once you pass Cheyenne, you will likely not have cell phone coverage, at least thats how it was 3 years ago.
