Flagstaff to Sedona? Safest way with a Class A + tow behind?

I did alt89 last summer all the way down to Cottonwood pulling my toad. Beautiful scenic road that was downhill to Sedona so maintaining the speed limit is not a problem. Biggest problem is slow moving rubbernecking four wheelers and very few places to pass them and they are not about to pull over even though they have six held up. CGs in Cottonwood are more reasonable but not great. I would take it again in my rig as you sit up high and can see better than in a car.
