Where in West Africa are you going?
My take: gasoline 4x4, especially 4runner/prado, is not the best option. The 4.0l will chug through fuel once you have it moderately built and loaded up. You'll be lucky to get 300 miles of range, which might be sufficient for most areas, but that doesn't leave you a lot of leeway for tangential explorations or safety margin.
Have you considered renting/leasing or even buying a used Hilux or Ranger? Those vehicles are all over the place in Africa.
