The truck in itself is wonderful. It uses way too much DEF fluid when pulling a trailer. The stiffer Springs in the rear are causing a rough ride with a trailer. Great power, love the camera system, love the handling, very quiet.

I've owned and operated many different trucks for either work or home and I'm constantly surprised by the performance, reliability and security this truck has to offer. It wasn't cheap but you really can't put a price on safety and comfort while towing a trailer long distances. The improvements GM made from 2019 to 2020 are significant and would strongly suggest you do your research before purchasing a different truck - they're not all created equal. Buy with confidence. I'm a believer and will never go back.

We just Got the new 2020 GMC 2500HD 4×4 Duramax crew cab . Wow what a difference it is compared to my 2018 GMC with all the same features. What a great truck . The team at Piehls GMC in Princeton,IL with CJ,Rob an Harold made the entire process a great experience. Thank you Brett

1000 miles away from home with large camper and 2500 GMC Sierra won't start. We have 2 cats and 1 dog with us. We bought truck for pulling our 5th wheel camper. At dealer for 3rd day. The main engine control module is out. We were told we were lucky they found 1 available. Yeh,, lucky us. We had a 2008 Toyota Tundra that we traded on GMC. It had less than100,000 miles, but we thought since we would be traveling so far a newer truck would be more reliable on highway. We were wrong. We were told yesterday truck would be ready this morning. Now, it's 4:30 pm and still no word. Read your reviews on GMC and keep looking. We only have a couple of days of vacation left and the weather here in Texas only got warm a couple days ago. Oh yeah, they found us a rental but its a Chevy Malibu. Pets aren't allowed in it and we planned on going to beach with dog when it warmed up. We have always had foreign vehicle makes except we bought a HHR. I spent every off day at dealer. Ignition, heater, ac steering wheel, brake. problems. I can't even remember everything that went wrong with it. Don't look to GMC for reliability!

I love love love my truck. It is stylish, powerful and durable. I am going to pull a 28' camper so I wanted a truck that I felt would do the job. I do agree with some of the other reviews, after many miles the seats are hard but that can be fixed with a lamb skin seat cover. I got a great deal on mine as it was a trade with 3,300 miles on it (guy traded for a Duramax). I would never drive the $10K difference out of it so I'm happy with gas vs diesel. The 6.6 engine has ample power for towing.
