John, we made it to Michigan using that route. The San Augustin Pass was the only challenge. Guy in Alamogordo told me it is worse going the other direction. How would you make the return trip? I'm debating taking I-40 to Flagstaff and then coming down to Phoenix. Not sure what the elevation challenges would be from Alb to Flag. Other option is to go down to El Paso and then to Tucson, bypassing the mountains.
