If I wanted "I don't care what I hit" power, there is a rusty CJ from my childhood memories, with 4x4 wood bumpers and railroad track sliders, that still lives on in my brain. Or were the bumpers railroad ties? That would make more sense. I shouldn't place much trust in my memories.
It depends on what your jeep is meant for. This jeep is being built for long-distance and light/medium off-road, with potential for heavy load-outs, and living out of; as light as possible, with as much stuff as possible. So no Rock-Crusher 3000 for me.
Simply said: granted, plastic steps are not efficient for rock-shattering, but just as 600lbs of undercarriage/body extras are not efficient for a 90 mile commute.
