I will be travelling to the Grand Canyon in Sept driving a truck and 5th wheel trailer. Is there any RV parks near or around the south rim. What about the North Rim? I see their are numerous tour trips, which is the best to take it all in? I see they have an all day trip in a mimi van, is it worth it or just do our own thing rather then being tied to a tour . as first timer's to the Grand Canyon, any suggestion would be helpful. thanks.
