i tend to agree its the driver.
i have seen a lesser rig with open diffs try and try an obstacle which a locked rig walked over and in so doing tear up the area. again if the lesser rig attempted a couple of times then stop and pull cable or get a tug there would be no damage.
i have also seen very capable rigs trying new obstacles over and over with different approach angles repeatedly till finally after twenty trys they make it. leaving huge undercuts and huge holes.
its the driver.
