Pat and his team did a great job.
Pat and his team did a great job. I purchased a new Tahoe online and traded my old in. They gave me about 15% more for my trade than Carvana and Carmax, and even picked it up. I purchased a wonderful new truck at a fair price. They arranged fair safe shipping. I would without question refer this dealership to anyone looking to get a vehicle. This was one of the easiest and best car purchasing experiences I have had.
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.

Absolutely outstanding!! AGAIN!!
This is the second time I have purchased from Country Diesels. I live almost 100 miles away, and traveled back to them once again, because I trust and believe in these guys and the trucks they sell. EVERY aspect of my buying experience was nothing short of first class. I will not go anywhere else, and I WILL be back when it is time for another purchase. Thanks so much Kevin and Chris!!
Love it.
I love the new features this truck offers. I would highly recommend this truck if your looking for a Diesel. I provides all the features and benefits you would want.

Great dealershio
Kaley and the rest of the crew were great. Gave me what I expected on my trade-in. No problems with the whole process. When I told them that I was going to check out another dealership, they did not try hold me back from going. Ended up buying from them.
