Fort Collins Dodge, Chrysler, Jeep, RAM review
The most important element of this dealership was the salesman. Joe Zielonko was super knowledgeable and a great fellow to work with. In my 6 decades of purchasing cars, Joe is in the top 5 percent. We felt very comfortable with Joe and we did not feel pressured. He listened very well to our needs. He is a credit to the organization.

Kendall Ford of Marysville review
The guys at Kendall Ford are more than willing to negotiate low pressure. I had a great experience second brand new vehicle. I bought there.
2020 GMC Sierra 3500 review
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.

2020 GMC Sierra 3500 review
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.
