Takes clearance to be best in mud, along with much larger, more aggressive tires.
Climbing needs power, as well as clearance and traction.
Short wheel-base is good for climbing over logs, but again, clearance helps, along with a front bumper close to the wheels.
"Off road" in Africa looks very much like some logging roads here, to me with deactivation trenches. Many pickups can navigate those, even my F350 with the short box.
