Personally, I liked the MJ as a DD better. I don't need more seating, and seem to spend a lot of time hauling stuff that could only be described as 'crap'.
As it is, in the back of my cherokee I have the seat folded down to make space for the spare tire, my stump chains, 4 boxes of stuff to go to the dump, my tool-boxes (in case I decided to hit the boneyard). The carpet is now a greasy, dirty mess. And I'm always afraid I'll roll it and have all the stuff in the back hit me in the head...
Had I not destoryed the cab, bed, and unibody on my MJ I would very well consider restomodding it and DDing it, and wheeling my XJ. Okay, maybe I'd not wheel the XJ. But the point is the MJ did really well on the street for me.
