First time to S.Dakota

.. just a thought... You said you're not prepared for boondocking but why not try dry camping in national forests or national parks - at least for a couple nights? Since you seem to like that type of scenery I really think you'd enjoy it - nice and quiet. You can stay right in the midst of the areas you want to see. Your Class C has a generator. That's all you need. Fill your fresh water tank and empty the others beforehand and you're good to go! Conserve water.. no long showers. I think you'd really enjoy it - at least as an option. You can get into some beautiful quiet places.
