yeah, your skill as a wheeler should diminish now that you have the locker. I suggest you learn to use it only when you have to, I like the 2 try method, try it twice with an open diff then try with the locker. You don't learn anything if you cheat the first time... I'm not saying having a locker is cheating, but don't just drive up to a hill and say, oh yeah, this is gonna need a locker. Think of it as a last resort, a piece of recovery gear if you will, and try to NOT use it, but revel in the fact that it's there for when you can't get up something.

Do you understand what I mean now by don't let it make you a worse driver?

Try, try again, then flip the switch.

The worst is that guys with stock Xterras will be able to get up stuff that you will need the Locker to get up. Why? because you now have an open diff.... It always sucks to do something cool then have a guy in a stock vehicle walk the dog....
