Who is the Sierra AT4 for?

The ‘Toy Hauler’ who wants a truck that can get the boat to the lake or the ATV’s out to the backcountry with ease. You like sitting a little taller than everyone around you on the road and appreciate the extra storage for all of your electronics that help you stay connected.

The family who needs the extra space for everyone’s ‘stuff’ and the interior comfort to handle any weather. The off-road options help you take your kids to seek out any new adventure with confidence.

The Sierra AT4 is unique…a combination of next-level interior and electronic features with the rugged, go anywhere off-road capabilities you need to enjoy the world around you. A truck that moves easily from dinner in the city to stargazing at the lake.
