Rt 89A Flagstaff to Sedona

I do NOT recommend driving anything larger than a crew cab pickup truck on that road due to the steep grade and hairpin turns. It's a pretty drive so take it in a toad but do not drive an RV into Oak Creek Canyon from either end (turn around space is almost non-existent). You would be better off taking I-17 south from Flagstaff to 179. Even that one can be a little bit tricky because of the stupid roundabouts that have become the rage here in AZ the last few years (I would love to get my hands on the morons who made that idiotic decision).
