You Had to be There
The current weather got me thinking about this, so my question is what about a Powertrax Lock-Right Locker?

Ah the proverbial "lunchbox" locker. The lunchbox lockers are very easy to install and function similarly to other automatic lockers (ie Detroit Locker). They are not quite as strong or harsh as a Detroit Locker but they are still an automatic locker and posses all of its benefits & weaknesses.
Really just gets down to what your vehicle is used for when deciding whether to select an LS, Automatic or Selectable Locker. Automatic lockers are nasty to drive on slick streets, ie ice, the ice storms that Houston and the surrounding area get periodically would make any automatic locker in a DD a real handful.
