This marriage sees the truck bed and body become one with the ladder frame. Owing to the body-on-frame setup, the suspension and brakes are placed on the chassis first, with hordes of employees installing the necessary parts quickly and efficiently. Depending on the chosen engine, a turbocharged 2.7-liter, 3.0-liter Duramax diesel, or naturally-aspirated 5.3- or 6.2-liter V8 is fitted to the chassis. There are two different transmissions: an eight-speed and a 10-speed automatic.

While this is going on, the body slowly starts to take shape. Special robots made by Japanese company Fanuc position the body over the chassis, carefully lowering it with great precision. These machines then join the two structures together.

Once this crucial process is completed, the side steps and windscreen can be fitted to the Sierra. The production line moves along at a glacial pace, giving workers enough time to complete their tasks and check for any issues.

The video could prove interesting if you're into trucks or just curious about the vehicle manufacturing process in general. It also gives us a brief look at how Toyota and Nissan build their respective pickups.

At the top of the rangesits the Denali Ultimate, a luxury car masquerading as a truck. Yes, it can do everything you expect of a full-size pickup, but the innards are filled with the latest technology, soft leather, and fine wood trim.

Soon,the fully-electric Sierra EVwill hit dealership floors with as much as 754 horsepower and 400 miles of range, but that vehicle's production process will be vastly different.
