The Toyota Tundra is a full-size pickup truck manufactured by Toyota since 1999. The Tundra was designed to compete with American-made trucks like the Ford F-150, Chevrolet Silverado, and Dodge Ram. The Tundra was initially built in the United States and has since become a popular option for those looking for a reliable and powerful truck. One of the most popular variations of the Toyota Tundra is the Double Cab model, which was produced from 2003 to 2006. This model offered a larger cabin than the regular Tundra, allowing for more seating and storage space. The Double Cab also came with a full-size rear door, making it easier for passengers to get in and out of the backseat. The 2003 to 2006 Toyota Tundra Double Cab was known for its powerful engine options and impressive towing capacity. The standard engine for this model was a 4.7-liter V8 that produced 240 horsepower and 315 lb-ft of torque. This engine was paired with a 4-speed automatic transmission and offered solid acceleration and good towing capabilities. For those looking for even more power, there was an optional 4.7-liter V8 engine available that produced 282 horsepower and 325 lb-ft of torque. This engine was paired with a 5-speed automatic transmission and provided even better performance and towing capabilities. The Tundra Double Cab could tow up to 7,100 pounds, making it a great option for those who needed to haul heavy loads. In terms of fuel efficiency, the Tundra Double Cab was on par with other full-size trucks in its class. The 2003 model had an EPA rating of 14 mpg in the city and 17 mpg on the highway, while the 2006 model had an EPA rating of 15 mpg in the city and 18 mpg on the highway. While these numbers may not be as impressive as some smaller trucks or SUVs, they were competitive for a full-size truck with a V8 engine. Inside, the Tundra Double Cab was spacious and comfortable, with plenty of room for passengers in both the front and back seats. The cabin was well-appointed, with high-quality materials and a user-friendly layout. The seats were supportive and offered good visibility, making long trips more comfortable for both the driver and passengers. In terms of features, the Tundra Double Cab was well-equipped for its time. Standard features included air conditioning, power windows and locks, keyless entry, and a CD player. Optional features included leather upholstery, a premium sound system, a navigation system, and a power sunroof. In terms of safety, the Tundra Double Cab offered a good level of protection for its occupants. Standard safety features included dual front airbags, four-wheel anti-lock brakes, and traction control. Optional safety features included side airbags, stability control, and a rear-view camera. Overall, the Toyota Tundra Double Cab 2003 to 2006 model was a solid choice for those in the market for a full-size pickup truck.
