2025 GMC Sierra 1500 AT4 4dr Crew Cab 4WD 6.6 ft. SB (3.0L 6cyl Turbodiesel 10A)
After 1 year of ownership my 2025 Sierra, babymax left me stranded. This truck only has 7000 miles. It has been 40 years since i had a vehicle leave me walking. Not only are the electronics bad, the transmission is already failing.
My AT4X is a beast!

2025 GMC Sierra 1500 AT4X 4dr Crew Cab 4WD SB 5.8 ft. SB (3.0L 6cyl Turbodiesel 10A)
⭐️⭐️⭐️⭐️⭐️
I couldn’t be happier with my 2025 GMC Sierra AT4X. This truck is truly the total package — it’s rugged, luxurious, and packed with features that make every drive an absolute pleasure.
The 6.2L V8 is a beast — it delivers incredible power and a throaty growl that’s music to any truck lover’s ears. Whether I’m towing, cruising on the highway, or just enjoying a spirited drive, … it’s smooth and strong every time.
The interior is a standout. The premium leather seats are both plush and supportive, and the heated and ventilated front seats with built-in back massagers take comfort to a whole new level. Long drives or tough days just melt away with that feature.
The sunroof adds a wide-open feel to the cabin, perfect for sunny days or starry nights. And let’s not forget the incredible MultiPro tailgate with the Kicker tailgate stereo system — it’s hands-down one of my favorite parts of the truck. Whether I’m out tailgating, camping, or just hanging out with friends, it’s awesome to have a high-quality sound system built right into the back.
The technology in this truck is top-notch too: the infotainment system is super intuitive, the surround-view cameras make parking this big rig a breeze, and the adaptive cruise control and safety features give me total confidence on the road.
Overall, my Sierra AT4X feels like a luxury truck that’s ready to tackle any adventure. It turns heads everywhere I go and makes me smile every time I climb behind the wheel. If you’re thinking about getting one — do it. You won’t regret it!
Great sale on a great truck!!

I just picked up the 2025 GMC Sierra 1500 Elevation Diesel with the X31 Off-Road Package, and it’s everything I wanted in a truck.
Diesel Power
The 3.0L Duramax Turbo Diesel is smooth, quiet, and full of torque. It pulls strong, whether you’re towing or just getting through daily traffic, and the fuel economy is far better than you’d expect from a full-size pickup.
X31 Capability
The … X31 package really adds confidence when the pavement ends. Skid plates, off-road suspension, all-terrain tires, and a 2-speed transfer case make it ready for dirt, mud, or trails without compromising everyday drivability. It feels rugged but still controlled, and the extra protection underneath is a nice touch.
Ride & Comfort
Even with the off-road suspension, the truck is comfortable and quiet on the highway. The Elevation trim gives it an aggressive look without going over the top, and the premium touches inside make it a comfortable place to spend time. Tech is easy to use, CarPlay connects fast, and there are plenty of charging options.
Overall Impression
The Elevation Diesel with X31 hits the sweet spot: power, efficiency, comfort, and real capability. It’s just as at home on the highway as it is on a back road, and it looks sharp doing it. If you’re considering a Sierra, this setup is hard to beat.
Side note: The vehicle details "Model" is not correct. They don't have my trim package as an option.
