2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Lynch GM Superstore review
They really made this a smooth experience.
They really made this a smooth experience. Especially when it came to the actual purchase of the vehicle. We dealt with Nick as our sales person and he was great at communicating with us and insuring any needs or concerns were addressed.
2025 GMC Sierra 1500 AT4 review
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Lynch GM Superstore review
I had the best experience buying my new Trax.
I had the best experience buying my new Trax. Craig Winger was absolutely amazing. He is very personable He was great about what I wanted and did not try to persuade me in any way. Just a great guy and you felt more like he was friend than a salesman. The whole Lynch family was great. Tom and Dan were great also. Just a great experience for buying a vehicle, the best I have ever had. Craig thank you I Love my New Blue Trax. Would totally recommend Lynch for your next vehicle purchase. 10 stars and more
2025 GMC Sierra 1500 AT4 review
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.
