It took me almost 2 years to decide between a KJ and a TJ Unlimited or Unlimited Rubicon, all the while my daily ride was falling apart. It's a tough choice if you can have either. Someone on here has both (Longarm I think). Yesterday on my lunch break I found what I would have gotten had the coin flipped the other way, an '05 Khaki Unlimited Rubicon soft top and I parked my Khaki CRD next to it.
I was immediately reminded of why I went with the KJ. It's bigger inside and out, it's a diesel, it's more comfortable, it's WAY cheaper. This is coming from a guy that is asolutely in LOVE with the I-6 engine that will no longer be available after this year. Very tough choice. I've been the 3 vehicle route and it's a pain - I wanted to enjoy what I drive, and drive it all the time - so I had to really think about the KJ vs. the TJ.
One after the fact piece of information that I've learned is that I'm averaging 22-24mpg in the diesel CRD around town, and a few other guys in town here with their Rubi Unlimiteds are averaging 12-14mpg around town in the same city traffic. If I was choosing between a gas KJ and the I-6 TJ, that would have been real hard.
If you are really going to use that Rubicon, and I mean REALLY use it, go for it. I figured out I could have gotten away with just a base Unlimited and never maxed out it's capabilities as it came with the D44 rear and most of the heavy duty goodies in stock form - but even that would have cost me a few more $k than the CRD Liberty - and once you go diesel - you'll most likely not go back.
Good luck with your decision.
