It's true that most trucks aren't worked like a truck but even in day to day unloaded driving they have to be working harder to some degree.
I just bought my first Toyota last year. In a couple years, I like to get a full size truck, but I have noticed how the Tundra just seems on behind. I almost consider a GM or Ford, because of that. But as those smaller displacement engines, for one, you have run on premium gas to get the rated hp and torque, and you have to drive like a grandpa just to get the good mpg's. Otherwise, they hardly do better than a V8. The word on the street is from guys that buy pickups to constantly pull and haul heavy is that the V8's just make better mpg's and the turbos give out early for then. But they do perform good. I think GM has it going good for them in shutting off cylinders.
