CHANGES FOR 2013: - Several Tundra models receive enhanced available options packages including the added safety of a backup camera with display integrated into the rear view mirror. Toyota's full-size pickup got its last update in 2010, with the addition of a new engine and transmission. Since then, it's seen few changes. The Tundra still gives up some flexibility to its domestic competitors in terms of configurability; the 11 variations (three 2WD and eight 4WD) pale in comparison to the choice available from Chevy, Dodge, and Ford. This is a nice truck, but Toyota lacks the reputation as a full-size truck builder to steal many buyers away from those American-branded pickups. It's also no longshot to suggest you'll get similar capability for less money in a domestic truck. The Tundra is available in Regular Cab, Double Cab, or CrewMax configuration. Bed lengths are standard (6-foot-7), long (8-foot-1) and short (5-foot-6). A 4.6-litre V8 is available in Double Cab configuration, while a 5.7-litre V8 is available in Regular, Double Cab and CrewMax configuration. Both engines use a six-speed automatic transmission and both come in two- or four-wheel drive. Regular Cab models come with long boxes in 4x2 configuration, and with standard or long boxes in 4x4 configuration. Double Cab models come with standard boxes in 4x2 and 4x4 configuration. CrewMax models come with short boxes and in 4x4 configuration only.
