If you've got the diff locker (I don't know how the '05+ models run) then you've got a pretty kick-ass wheeling machine.

Rock sliders would be a very good idea to help protect your rig. Check out http://www.shrockworks.com

Oh crap.. I just noticed you're in Maricopa... you are sitting smack in the middle of a HUGE Nissan offroad community. You couldn't possibly be in a better spot if you want to offroad a Nissan! Check out the SWANKy forum at http://www.nissan4wheelers.com . Tell 'em Kaiser sent ya.

I'll be driving out there in March for the AZ-6 run
