I get it, but personally for me..if I was looking for a 2WD family vehicle, I wouldn't consider a 2WD T4R. Mostly because of our Canadian Winters. Any 2WD pick-up truck doesn't do very well here. Wheel Chains and Studded Tires are illegal here.
Most people with 2WD trucks (or any RWD only vehicle really) typically have to weigh down the back end with sand bags or steel plates to ensure traction during our icey winter months.
So yeah... for me... the 4WD button does get used a lot during at least one half of the year even if I'm only going to the local grocery store. My street isn't always the first to get plowed after a dumping of snow, lol.
Naturally, I commented on the fact that the T4R in question was 2WD because the OP hadn't specified the specifics of his situation and intended usage at that point.
