Maybe alittle late on this one, since it has evolved into a history lesson, but I have a new Ram Power Wagon with lockers, Warn 12K winch, electric disconnecting sway bar, skid plates, 33's, Rock Rails, and Hemi from the factory make for a pretty damn tough truck. BTW I also have a '05 Grand Cherokee which is the most smoothest riding car I have driven.
So as far as off road capable The Power Wagon is pretty friggen tough
