Those lunch box lockers are supposed to behave like a normal differential on pavement but they are noisy when they kick out one side on turns but I can't hear mine. I have read people say not to use them in snow and ice. Something I'm sure you'll run into in Wyoming. Just a thought. I have one up front in mine but I never intend to drive in snow or ice. I thought mine was pretty cool when I put it in but I kind of have mixed feelings about it but I don't plan on doing a lot of wheeling so it probably will stay there for forever.
