The locker is awesome if you use your truck as a truck. Pretty much eliminates getting stuck. However, there are a few things that might bother some people:

1. When letting off throttle and reapplying, one wheel will be powered until the backlash is removed. This tends to make your truck dart to one side of the road. Not a scary amount, but something to be aware of.
2. When letting off the throttle, the locker will uncouple and send a "pop" vibration up the driveshaft. If you don't know what it is, you might think something is wrong in the drivetrain.
3. Quick acceleration around corners will almost always cause a chirp of one tire as there is no differential (one wheel has to turn faster than the other in a corner).
4. Because of #3, driving on snow or ice with highway tires could send you into a spin-out.

All four are not enough for me to ever want to go back to an open diff. So much better with a locker. I hate getting stuck on a tiny mud puddle or wet grass.
