Drink lots of water; flavor/vita packs nice
Wear rugged, long sleeved, loose fitting clothes
Temps ranged from mid 60s to 100s (°F)
Dust/sand/wind – protect face, optics, electronics
Travel adapter AND converter essential; rechargeable AA batteries are nice; ditto thermometer.
*Handheld GPS and 2-way radios nice if you can get them in-country*
