If you really want to enjoy the Grand Canyon my suggestion is to forget the rented camper and concentrate on a great Grand Canyon trip. Fly to Phoenix, rent a car/van and drive to Williams, AZ. Take the Grand Canyon Railway to the Grand Canyon. The Grand Canyon Railway has several packages including lodging, food (which is excellent) and the Train ride to the GC. You can also do a package that includes a night or two in the Grand Canyon hotels. Plus, Williams is on old Route 66 with plenty of side trips nearby.
