Ideally. An Ford F600 4x4 with the old Cummins 5.9 p-pump or maybe powered by an Air-Deutz diesel. Would be have an flatbed, with toolbox storage or a dump bed and some armour up front for pushing and animal collisions.
I've seen Air-Deutz literally work in the bowels of hell deep underground and operate at unreal engine temps and unreal ambient rock temps.
