I guess I am odd man out. I have had my present 2WD since 2001. It does have a limited slip rear end. I have owned a truck since 1968, and none were 4WD. I do not go off road with my TC. While it could be nice to have, I have never needed 4WD. Weight wise, I have compared my truck with 4WDs of the same year and model. The 4WD is almost 900 pounds heavier. My truck scales at 6200 pounds. I have been told by my 4WD friends, the 4WDs can get very pricey in repairs to the front axle.
I have had my 2WD in snow several times. I have chains and never have used them. Hard for me to imagine getting stuck in grass with a 4000 pound TC loaded. I do not buy highway only tires.
I bought my 2WD truck used from an estate and got a super deal. If I were to buy a new truck, and did so every few years, I might go with a 4x4 due to resale/trade in value. If I used my truck off road as some folks do, I would go 4x4. As it is, I tow my 4x4 Samurai for off road use.
