Dealer Description

The 2020 GMC Denali 3500 HD Duramax is a beast. Pulling a conventional 10,000 lb trailer over mountain passes is a whole new experience. Staying at the speed limit up long steep grades did not change the engine temperature. The new 10 speed transmission is so smooth you can't feel it changing gears. This is my second GMC Denali Duramax, first being a 2016. I debated trading in for over a year, and I am so happy I made the trade. Trailers always exceed the tongue weight posted on them, and in my case it came in at 1450 lbs. That exceeded my truck's posted maximum. The 2020 dually posts a 2,000 lb tongue weight, so now I can front load the trailer, and that reduces sway. If you can afford it, and have a heavy trailer, buy the truck!
