The Toyota Tundra isn't just big; it is, in fact, the most imposing half-ton truck on the market. In order to power this hulking mass, Toyota calls upon a 276 horsepower 4.7-litre V8 and a 381 horsepower 5.7-litre V8. It boasts really impressive towing capabilities and performance. It offers first class comfort, but its reliability is not as seasoned as with other Toyota products.
