Ward,
We also have a 45' with tow. If you decide on going thru Globe and on up to ShowLow, you'll most likely not arrive as a happy camper. We stayed at the casino in Pinetop, a very nice campground, and did not take 60 South upon the advise of a Sheriff's deputy who advised us it was limited to 40'. We took his advise and went south using AZ 260 to AZ 87 through Payson. Very enjoyable drive. AZ 188 has about a 10 mile section that is gravel so that was out completely. IIRC there is a road restriction sign outside of Globe on US60. If you do decide to go that way, there a nice campground at the Apache Gold Casino in Globe. Personallly, coming from the South I'd take 10 North to 202 East to AZ 87 North and bypass Phoenix that way. Another shortcut would be 10 N to 202 E to 101 N to 202 E to AZ 87 N but it's easier to simply stay on the 202 which is a loop system around the Phoenix area....Dennis
