I am planning the road trip that takes me from South Dakota ( Mount Rushmore) to Yellowstone down through Utah to the Grand Canyon. Can anyone tell me how many miles this is roughly ? I want to hire an RV for this trip as will be travelling with my mum and gran ( 95 !). Would it be better to pick up an RV and start Grand Canyon end or is it just as east to start at the other end ( South Dakota) and can anyone recommend a good hire company ?
