Im in the market for a full size gasoline pickup for towing and hauling. Doing ALOT of homework, and most of the different truck brands have power bands at around 4000 rpm. (Lowest was ecoboost @3500) That seems awful high? Wouldnt you want to engineer the power band closer to 2500-3000 rpm where most tow rigs cruise at highway speeds for the sake of fuel efficiency?

Nah. When a vehicle needs maximum power will not be when it needs efficiency. If a truck’s power band is at 2,000 rpm then it is not going to have much actual power in that power band. Sure, it will be efficient while running at max power, but why would you want to be running max power when cruising on the interstate? You need power most when accelerating.
Power bands will naturally be at higher RPMs due to the physics of engines – power is RPM times torque. Thus, as revs go up, so does power until torque begins to drop.
