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.

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.

It was a pleasure working with Jimmy Wolfe.
It was a pleasure working with Jimmy Wolfe.He was the last person to find a solution to my problem.My 2018 Chevrolet Traverse had a transmission issue: it wouldn't start.I went to several dealerships to buy one, but because of my credit score, I didn't get the attention I deserved. Jimmy was able to find me a car that allowed me to continue working.Thanks to him,I can keep doing what I need to do instead of staying home unemployed.Thank you, Jimmy! Keep up the good work!
