We are planning an extended trip to Arizona in May 2014. Plans are to fly into Tucson and get rental vehicle. Travels will include Ramsey Canyon Preserve, Chiricahua National Mon., Picacho Peak State Park, Spur Cross Ranch, Sedona Red Rock Country, Granite Dells, Oak Creek Canyon Loop, Petrified Forest (27 mile scenic drive)/Painted Desert, Hopi Reservation, Canyon de Chelly (16 m So Rim scenic drive), MVNTP (17 mile Wildcat Trail), Page/Lk Powell, No Rim, So Rim (most GCNP touring will be hiking), and to Flagstaff for departure/return vehicle. I have mentioned the places that I could foresee had any potential for vehicle clearance issues. Any advice on renting a vehicle that will do the job for us would be appreciated. What rental companies have high clearance and which vehicles are those? Thanks much!
