Leaving New Jersey for Red Rock Spyder Rally in September, right after Spyderquest, with the RV and Spyder "in tow". Need recommendations on routes (less mountainous) if possible, as wife doesn't like riding the RV on mountainous roads. Also need recommendations on campgrounds, National Parks to visit, and time needed for each park! Great eatery information, on the way out and back, will also be graciously appreciated. Thanks in advance!! Chuck and Carol
