So far, I wouldn't change a thing, from the Jeep platform to the modifications. I had an idea of all the modifications that I would do so the Sport S was the perfect canvas. I knew I would be installing ARB Air Lockers, so no need for the Rubicon. And the diesel wasn't available in the Mojave which I was set on for the torque of the diesel. If it were available, then I may have gone the Mojave route due to the stronger rear axle (axle tubes are thicker than all other models, including the Rubicon) and reinforced frame. Now, if the 392 was available in the Mojave which sounds like it may be in the near future, I would have considered it but probably still stuck with the diesel. Have about 11,000 miles on it and still loving it. If you are going to either Overland Expo Mountain West or Overland Expo West, stop bye the Mule Expedition Outfitters booth and check it out.
