I work from home and drive maybe 6K miles per year, so the fuel costs and emissions aren't a significant consideration for me. But there's something in the bed almost every weekend, and even when there isn't, there's usually a kid or three in the back seat.
If you don't have a family, or you automatically call a handyman when something breaks, I can understand why you might not want or need to own one of these magnificent vehicles.
But for many of us, these trucks are carefully considered purchases that solve a lot of problems.
