Alec was GREAT to work with.
Alec was GREAT to work with. When we initially called he immediately sent links to the trucks we spoke about. Was knowledgeable about the truck which showed when he walked us through it and went through all the interior gadgets. Tony and Nick (sorry if I got nicks name wrong!) but Tony was great help when spoke to him then Nick when he closed it out going over all the options for additional warranty etc. top notch up and down. Highly recommend based off the experience and to add to it we searched most local Chevy dealerships and mauer was the best priced.
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.

always professional and through service.
always professional and through service. Very courteous and helpful staff. Very pleased with care of my vehicle. Clean and pleasant facility. I always feel well cared for.
Great luxury ride with great pulling capabilities.
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.

Myron was great.
Myron was great. Very personable and not pushy. He didn't deal much on the price but it was below book and in the end we were happy with what we got. The vehicle is exactly what we were looking for. Molly was great also with her big screen paperwork and helping us make a decision on the extended warranty which we purchased. Thank you White Bear Lake Superstore for a fantastic experience.
