I've been doing some preliminary research on first Taco purchase and I am leaning towards the access cab, 4 cyl, AT, prerunner. My interest in the pre runner is based on the higher stance and thus easier for me to enter and exit the cab. Here is where the confusion comes in. I've also gotten the impression that the prerunner has some capability of locking the rear differential but I don't see anything to this effect on the Toyota "build" website.
Is this locking feature inherent with the prerunner or is this something that requires after purchase modification later on?
Thanks for your comments.
