here's another vote for the Xterra, i've thoroughly enjoyed mine. they're pretty capable on stock suspension with just the rear swaybar removed. i've got the off road version with the factory rear locker, skid plates and billstein shocks.
Stock:
2in lift with rear sway removed
that said, i had a liberty limited rental last weekend that was not bad at all. the crappy dbw pedal and 3.8 were less noticeable with the automatic
