Low Clearance, Lordsburg to Globe to Apache Junction

Just stay away from this one in Durham, NC: youtube vid. A couple of FWs didn't make it. :E

When an RV manufacturer lists a height, is it to the top of the highest object on the roof or is it to the roof surface? And can you assume the manufacturer is accurate enough or should you measure it yourself to be certain?

I google mapped that tunnel west of Globe; the sign says clearance is 13' 3". That's a little too close to my 13' 1" for my comfort zone. You know, if I mismeasured by 1", and if the highway dept added a little asphalt, BAD! Thanks anyhow guys.

Came that way in January, no problems good road.

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.

No problems. We've done it with our 40' MH. I don't recall any bridges to go under.
