went that way in November in my MH there is a tunnel just east of Superior, AZ but west of Globe that is 13' 6" otherwise you are good to go.
Also at the New Mexico Arizona border is a no longer used weigh station that I have spent the night at.
Edit
There is a 7% downgrade that is quite long before the tunnel so make sure you have good brakes and use the safety stop to check your rig and cool the brakes before starting down if you have been using the brakes frequently.
