Usually, new trucks nowadays aren't fuel efficient. What the dealer told you is quite true. In order for your truck to run better, a bigger engine is needed otherwise, similar to older trucks that roars every time the engine is running.

Have you tried cheaper fuel efficient cars? For instance, an Isuzu Crosswind. It's an SUV yet fuel efficient compared to its other competitors. It has smaller engine and wow, from a little far, you would hear it's engine as if it's crying for help. Why? Because compared to a typical car, it's a little heavier yet it has smaller engine. The engine somehow exerts effort in working with the car.

If you really opt for better mileage, maybe choose a different car. How did you buy Tundra? If you can have it swapped if you really want to, then try choosing some other cars. But think about it first. Tundra are pretty good trucks.

By the way, I like Tundra. :) I like trucks! ^^

props to fallen_angel21 for a good answer, i'd just like to add a note about engines.. the most fuel efficient engines are large diesel engines. A larger engine gives better economy because they are capable of extracting more power from a given amount of fuel. Also, when you do need to speed up, a larger engine has the power to do it using less fuel, again simply by being bigger. superchargers also help at extracting more power from the same fuel, by further compressing the air into the engine. superchargers generally provide a very small amount of compression at low revs, but any extra helps
