Reg cabs don't get Atrac only trac which kinda sucks. You gotta spin the crap out of a tire to get it working, but it could get you out in a pinch. I put a Truetrac rear differential in and it really helps the truck hugely in every day use, as well as on trail. Only 420$ but does require full reset of gears. Get an intermittent wiper stalk, and be careful with your rear bumper, they suck.
