If you do any driving to Reno/Tahoe, I'd poke around a bit for the AdvanceTrac option. First, for someone that doesn't drive in ice and snow much like someone from CA, lol, it is extremely helpful when you do.
And second, the AdvanceTrac equipped trucks have an electronic panic assist feature that works well, and is not intrusive, but the non AdvanceTrac trucks have a mechanical panic assist feature that can feel pretty odd under certain circumstances, particularly in heavy traffic where you might have to stab the brakes quickly, but not hard.
And third, it can be turned off for monkey business
