Yep, 2WD here. Ordered it on purpose like that, dealer did a "swap" with another dealership to get the truck. I tow constantly during the summer, landscape equipment trailers and/or camping.
One big advantage? My truck is NOT 10 feet in the air! I can actually get in and out of it easily.
Would I like 4WD? Sure. But I'm happy with mine as is. I grew up with rear-wheel-drive large cars, so I can drive in sloppy conditions. I also put on actual, real snow tires (not the "all season") for the winter.
Having said all that, when I went to buy the truck, if the dealership had a 4WD version on the lot with the options I wanted, I would have bought that if the price was similar. As it was, I paid $$$$ less for mine.
