We are planning a trip in June from Wisconsin to Mt. Rushmore, Yellowstone, and Grand Canyon. We will be traveling with a 2007 40ft Winnebago Vectra (400HP) pulling a Jeep Commander with a Blue Ox Adventa II. Additionally, we will have a family following us in a 30ft class C (renting the unit). Does anyone have any advice on routes to take and not take. Campgrounds to stay at and ones to stay clear of? We take care of our coach and don't want to put us or the coach in a bad situation. We are looking at leaving June 18th and being gone for two weeks. Any advice is appreciated
