While the first generation of this model were compact trucks, since 2005, this truck model has been a mid-sized pickup. Buyers can choose between a 2.7-liter engine or a 3.5-liter V6 engine, and they also have the option of choosing between a five-speed-manual transmission or a six-speed automatic transmission. The truck is also available as a regular or crew cab, and buyers can choose between a long or short bed. Some models come equipped with off-road functionality while others have the revolutionary CRAWL mode allowing the truck to control the braking and acceleration while the driver does the steering. As of 2018, part of these trucks are built in San Antonio, Texas, while others are built in Baja, Mexico.
