I will be traveling in my class A MH with a toad I will be coming from Winslow AZ to Phoenix AZ! I see that going thru Payson AZ looks shorter than going to Flagstaff then down 17! Is this a good road...
If you are heading to the east valley (Scottsdale, Mesa, Tempe, Gilbert, etc), going via Heber and Payson is the way to go, although some of that route is without shoulders, and you have to be carefull through Star Valley as they have photo radar about every 100 feet. If you are going to Phoenix or the west side, taking the interstate may be more efficient.
