only thing needed for driving any vehicle in adverse condition is just knowing how to drive...
i have had everything from a mustang, rx7, elcamino, 2wd f150, jetta, you name it, i have had it... all those vehicles sucked, never once stuck. never once in an accident ( other than from me ephin around once doing donuts too fast (mustang)
since then i have bought 4x4's, and really had no issues @ all, i had an 01 lhs fwd for my winter ride last winter...
the tundra with 4x4 should do just fine as long as you know how to drive, use your head, and have good tires.
practice in a parking lot helps. this can not be preached enough. i love winter, i love driving in winter, i even kinda love snow... i do hate the cold tho, that just flat out makes me ache and hurt...
ill drive anywhere in winter, the gf and her fam won't go out, i drive to them, i have brought pizza, i have left there when they think i need to stay...
its only snow.
its the ice and freezing rain thats a pita.
and 4x4 goes better, stops the same ( for the same weight 2wd vehicle)
tire siping helps if you do not already have a good winter tire.
studding is not legal everywhere just like chains/cables....
keep the tank full in case shit happens and you are stuck or road closed and have to sit so you can keep it running and keep you warm.
