Our first visit.
Our first visit. Kevin the service manager was so helpful and Daniel our service writer was on top of all questions we had and our vehicle was done when promised.
Truck is a Solid vehicle overall.
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.

Bought a used 2018 F150
Sherry was easy to work with and made buying my truck hassle free. I would recommend this team to anyone.
Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

I was interested in a new GMC Acadia, specific features
I was interested in a new GMC Acadia, specific features and model. Zac Taylor worked very hard to bring a vehicle from the Colorado Springs store. He had everything outfitted as needed, worked out details remotely, then delivered it to me in the mountains. I drove away a great new vehicle at an outstanding price point. Thank you Zac for all of your hard work during this car purchase!

Best Car Buying Experience EVER
I have bought a lot of vehicles in my life time but this was by far the easiest and most pleasurable car buying experience I have ever had. I sent an email to the dealership around 1:45pm to inquire about a car, drove to the dealership at 5:00pm and drove home at 7:30pm that same day. Ricky in sales was amazing, easy to deal with, I told him what I needed and he took care of it without a bat of an eye!! I will refer anyone to this dealership and specifically to Ricky Pim. Thank you guys!! you are the best! PS - Finance guy, equally as great!! Jersey!

Everyone was professional and no pressure sales. A number very no nonsense dealership. I would go back to purchase again and would recommend to friends to go to Trans West GMC.
An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

Great experience with Berkenkotter Rastle Rock.
We had an excellent experience working with Dan & Wade on the purchase of our new vehicle. The sales team helped us through the process and were incredibly patient. Used vehicle prices are out of control and it's comforting to know there are car dealers that go the extra mile. I would rate our buying experience 10/10. We will be back when looking for another vehicle. Give them an opportunity to earn your business!
2024 GMC 3500HD AT4
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.

We had the absolute joy of working with T while we bought
We had the absolute joy of working with T while we bought our vehicle. T went above and beyond in so many ways - by coming in on her day off to help us out, adjusting her schedule to accomodate ours, being open and honest about the vehicle we purchased and the dealership itself - she was able to answer all the questions we had. We even had a small issue (no one could have known at the time of purchase) pop up a week or so after we purchased the vehicle and T was able to get it fixed for us, no problem. And - you know how buying a car usually takes all day? Not here. It took less time than any other place we have bought a vehicle, which is amazing. Thank you, T! You are the best!

Sales and finance teams were extremely flexible and
Sales and finance teams were extremely flexible and attentive, listening to my concerns and working to find solutions. They supported 2 different test drives when I had a concern about a specific driving condition, being extremely flexible working around my schedule. Cam, Austin, and Alec worked together to provide answers to all of my questions regarding financing and extended warranties. When a last minute issue arose on a Friday afternoon, their maintenance department obtained the part and swapped it out on a Saturday morning to allow me to pickup the car that afternoon. Communication was excellent, receiving 2 status updates that morning.

Big Step Up
This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.
