The Navajo Nation spans the Utah-Arizona border; many vendors sell genuine jewelry and crafts. Support local artisans by buying directly.

Gas prices tend to be higher in remote areas; budget accordingly. The best strategy is to fill at Monticello, then again at Moab or Blanding, and at Kayenta or Tuba City before crossing into Arizona proper.

Cell service is patchy. Verizon and AT&T have coverage in towns but dead zones in canyons and on tribal lands. Download offline maps and GPS coordinates for critical waypoints. Carrying a paper map is wise.
