Easy drive, no steep grades anywhere along the route. The climb to Flagstaff is very gentle, but you'll gain about 2000 feet elevation along the way.
Depending on time of the year, it can be very windy in the desert. That can make driving a bit tedious. Slow down if it's windy. Had to pass by a 5th wheel on its side that blocked the entire I-40 west bound last summer. Not easy to do in a class A.
