This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Great Buying Experience at Valenti Toyota
The team at Valenti Toyota is personable, professional, knowledgeable and experienced. They listened to what we were interested in, and they worked with us throughout the purchasing process. Sales consultant Steve Macomber was especially helpful in assuring that we felt comfortable and informed from the initial contact until we drove away in our 2016 Camry. He displayed a thorough understanding of both the vehicles and the process. Sales manager Rocky Sposato and business manager Scott Morrow were direct, honest and straightforward. Overall, we were treated as a member of the Valenti Toyota family from the moment we walked in the door.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

They turned what is normally for me a nightmare into a dream! I can’t say enough about Brustolon and their whole team! They explained everything to me in extreme detail. Made sure I understood everything. They really had my best interest in mind especially when it came to the financing. They got me an unbelievable rate. My credit union couldn’t even beat it. These guys are great i’ll never buy a car anywhere else!!! Thanks again Joe and Chris!!

Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Most convenient options on any vehicle I've owned.
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.
