We have driven US-60/AZ-260 from I-25 to Payson a number of times. It is a good route. We pull a 32' travel trailer and have had no problem getting fuel. However, we have a diesel and can use the truck pumps. I start looking for fuel at half a tank. We also do not drive more than 250 miles and often unhook to tour the local area so their are often opportunities to fuel without the trailer in tow. The Safeway on US-60 in Show Low is a common fuel stop for RV's.
Along this route is
the Very Large Array. The
Ghost Town of Kelly and some other Ghost Towns are near Magdalena.
Take a break in
Pie Town.
There is a
BLM campground at Datil Wells.
