Watch MotorTrend Presents: Electrifying the Outdoors

"I'm so excited, I don't even know the name of where the heck we are." It's the final leg of the Trans-America Trail adventure, as Conner Golden and a returning Christian Seabaugh direct the Rivian R1T through Oregon's gorgeous high deserts and lush old-growth forests on their way to the Pacific Ocean.

"A surprising lack of banging things is the technical term I'll use." Hell's Revenge is just the beginning as Scott Evans and Alex Stoklosa push the Rivian R1T to its limits on Leg 4 of the Trans-America Trail, pointing the truck towards every obstacle they can find across the state of Utah.

Sean Holman and Frank Markus may work on opposite sides of the business, but they'll need to come together to tackle muddied two-track roads, multiple 12,000-foot alpine passes, and even a herd of goats as they direct the Rivian R1T through the various terrains of Oklahoma and Colorado on Leg 3 of the Trans-America Trail.

"I'm schvitzing through my shirt, and I apologize." It's hot, it's humid, and it's drop dead gorgeous. After a handoff from Leg 1's Christian Seabaugh and Aaron Gold, Miguel Cortina and Jonny Lieberman navigate the Rivian R1T through the South on Leg 2 of the Trans-America Trail.

Tackling the Trans-America Trail -- a route of interconnected, non-paved roads that runs from the Atlantic to the Pacific Ocean -- is hard enough with a gas-powered vehicle. But what about in an electric pickup truck? Strap in with the editors of MotorTrend as they trek from coast-to-coast via the TAT in the groundbreaking, fully electric Rivian R1T.
