Off-road, real off-road capability is low range and off-road tires to me. When I had my 1974 Cherokee, we left the pavement and switched to low range, never to shift back until we came back to the road. The first difficult mud bog, the first sand trap, the first rock garden proved the point.
You don't have to be rock crawling mountain goat bent to understand the need for low range tip toeing and the torque multiplying effect low range brings, as you traverse the off road.
Now whether you plan to use it, really go off-road, that's your decision.
BTW, the Jeep film shown of Moab, we did that trail many times. It's spectacular. Yes, low range is required IMHO. And yes I recommend the V-8 for this, off-road, torque is king -- But street tires are out. Blow one out, rocks have their evil ways, like where those Jeeps are shown in the above photos, heap big trouble.
