The 2012 JK I had last had the 3.21 axle ratio, and with the newer engine and auto tranny was actually quite pleasant to drive. With the 255/75-17 tires, it still would go 80 on the freeway easily, and got 17-20 mpg, so it was no slug, even with the 3.21 axles. 2-door Sport, though. I know the Unlimiteds are heavier...
Nice color. Happy wife, happy life.
