We're in Jackson, Wyoming with the 2020 GMC Sierra HD AT4. It's GMC's answer to the RAM Power Wagon, but with twice the payload and 74% more payload. If you want to tackle almost any terrain and tow everything from a boat to a gigantic horse trailer, this could be the car for you. In Wyoming though, it's better at causing traffic than it is at navigating it.
