This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

Have purchased a lot of different cars at different dealers and the three I delt with there were great. Best experence ever. Derek , Adam, and Grant treated us like royalty. Purchased a 2025 Teguan for my grand daughter 11/14/25 and went back 11/15/25 and bought one for my wife. No presure sales and two the point , no haggle sales. I have probably purchased over 50 vehicles in my 78 year history and this is like sales should be. First time volkwagen purchases.

Best truck I have ever owned. Used to tow a heavy RV. Wonderful comfortable ride. Highly recommended this truck. I drive it as my primary vehicle.

Very friendly and helpful. Allowed us to test drive and followed up nicely. Did not have exactly what we were looking for on the lot but tried to help find one.

This review is for Jason Gross service manager. I needed an engine replacement in my Ford edge due to coolant intrusion and after talking to Jason within a few days, he had ordered to parts. I brought the car in and a week later I picked it up and it’s been running great ever since then. Thank you again, Jason for all your help you made all the difference in the world, getting this done right and in a timely manner, thank you ! Jerry D.

Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

awsome poeple smooth dealings will be buying amoot of cars from them. cause they have wverything you could want from super cars to pick up trucks or any make modelmof car you can think of clement is awsome.

Very easy process. My salesmen Andrew was great! Was able to negotiate price. No over msrp accesories or extra fees. ! Thanks

I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

Tried to help me but im in Louisiana. Have a grade in that's an issue. Overall Andy tried

A very special Thank You to both Chad Sigsworth (Sales Associate) and Patrick Amann (Service Associate) who both assisted in the replacement of my engine. Both gentlemen were dedicated from the begining to the end of this replacement. They both stayed right on top of things and kept me well informed until the job was completed. I will always purchase any future vehicles through Dave Sinclair due to their honesty, dedication, and treatment of their customers. They have one of the best staff I ever had the pleasure of working with. Keep up the great work. Sandra Hearn
