I feel kind of silly asking this question, since I used to drive in the snow all the time, but...... I am thinking of buying a Nissan Frontier, and since I live in Florida, I don't really have a need for a 4wd pickup. But, I used to live in NH, and would like to move back in that direction in the next few years. That would mean having to deal with snow again. I don't want to be stuck (ha ha) with a vehicle that is undrivable, but I also would rather not spend the extra $2500 or so on something that I may not need. Would I be able to get by with a 2wd if I put a bunch of weight in the back, and get a good set of snow tires? Also, a locking rear diff is an option on the Frontier, would that make any kind of difference in the snow?
