I guess if someones's top concern is driving the largest, heaviest, "safest" SUV/pickup out there and don't give a rip about the lives of other motorists, they could always drive a Navistar International 7300 CXT. It would flatten a Ford Excursion or a H1 and would only lose going up against a fully loaded semi or cement truck (or an M1 Abrams). It's the current top gun in the SUV arms race.
