Powered by GMC, Built by Overland Expo

Starting with the venerable 2022 GMC Sierra 1500 AT4X, we’ve outfitted it with the best overlanding gear on the market today.  Stay tuned here as Overland Expo’s staff of seasoned overlanders take the rig on their own adventures throughout the year capturing stories and demonstrating just how good the AT4X and our ultimate gear is on the trail.

1500 AT4X

Thanks to the rise of overlanding, 4×4 trucks and SUVs are more popular than ever before. The handful of factory overland-ready rigs on the market are supported by hundreds of aftermarket parts makers that can transform a capable stock rig into a trail-conquering overland machine.

However, sifting through the virtual sea of parts to find the best, most solid and reliable pieces of equipment can leave your head spinning. After all, just because something looks cool doesn’t mean it’s tough enough to withstand a hundred thousand miles of overlanding.

To cut through the noise, and further inspire novice overlanders to get outfitted, inspired, and out on their own overland journeys, Overland Expo is building its own Ultimate Overland Vehicle.
