You can buy the 2007 Toyota Tundra in more than 31 different styles. There are five basic configurations and three body styles: Regular cab with two doors, Double Cab with rear-hinged rear doors, and the massive four-door CrewMax. Of these three, the Regular Cab and Double Cab come with your choice of a 6.5 or an 8-foot bed; CrewMax models get only a 5.5-foot bed. There are three trim levels: DX, SR5 and Limited. The DX is your two-door work truck, and the Double Cab and CrewMax are available only in SR5 or Limited trims. Power wise, there's a V6 (DX only) or two V8 engines from which to choose, and either a five-speed or six-speed automatic. Four-wheel-drive is optional on all body styles.
