Prerunner with locking rear?

Still trying to decide on a new vehicle. Not sure I really need a 4x4 - only need it sometimes. Can I buy a stock Prerunner with a locking rear differential? That might be the way for me to go.

Thanks.

 

where do you live? ever needed it in past?
all my previous tacomas were 4wd and i only needed once when i lived in virginia but even then i could have used 2wd. i bought my current prerunner with the rear diff so that if i got somewhere that i shouldn't be it could probably get me out. it took me some time to realize its ok to not have a 4wd and that i didn't need it. a good set of tires is also an important key to it. hope this helps.
