Do any of you have lockers on your 2WD truck? How does it go in the snow and/or rough conditions? I know it's no substitute for 4 WD. I have 4 WD in my truck but it's a waste as I don't off road but I do live in New England, so it snows here, but they clear the roads so quickly so 4 WD is largely superfluous. I'm looking at a 2 WD (with locker) NISMO model Frontier.
