Since you're planning on wheeling with it, look for a Rubi TJ. You'll get the D44 Axles that way, and the I-6. And it should be cheaper than a comparable Rubi JK.
I just like the looks of the TJ better. I test drove new JK's and JKU's. Ended up buying my TJ. It is older, being a 2004, but it had low mileage and was taken care of. Stock still, but I'll upgrade at some point.
