Best truck I have driven! Highway speeds are great and feels like I’m driving a Cadillac.

Reviewed a 2021 GMC AT4 Crew Cab 4WD on Jun 20, 2024

When the sales rep said “It has everything but the kitchen sink” I’m pretty sure it has those in it too! This is the most rugged yet luxurious truck I’ve ever ridden in much less owned. I can’t say enough about the features that makes everything from lining up with a trailer hitch to getting warnings via through the seat vibration when getting too close to something when backing up. Heck it even has a forward facing camera that helps up front. Two thumbs all the way around!
