THe Nitro is a KK with the good bits taken out, not the other way around.
I test drove the CRD in both the KK and JK, and found that the KK had a heap more punch. For touring I've heard that they are as comfortable as the KJ (which is a great tourer) , and with the slightly bigger interior that would be good. As well you can put bigger tyres on so that would be another plus, Plus there is already a lift on the way so thats a bonus as well.
Don't know of someone personally that has the moon roof option, but, have seen them driving around. I mean, it would be cool, but, I would imagine with age, the roof might be a little bit of a issue, Leaks, tears, rattles, that sort of thing, but thats soft tops for you.
