Engine Grade Braking is for going downhill on highways, works in conjunction with cruise control and the Exhaust Brake. I've read use Tow/Haul mode button to amplify Engine Grade Braking. Hill Descent Control is designed for rough country downhills at slow speeds. Therefore on AT4s and Z71s. From GMC: Hill Descent Control Uses antilock braking to help provide a smooth, controlled descent in rough terrain Activates by pushing a button on the instrument panel Works without the driver pressing the brake pedal

We went from the Silverado 1500 NHT in my tagline to the 2018 All Terrain and have really enjoyed the GMC. Getting ready to order a 2020 AT4 3500HD long bed for the increased capacities. We are keeping the 1500 for around town, I still enjoy the kick in the pants I get from the 6.2L. P.S. I took the All Terrain to Jackson WY 5 weeks ago after I put Goodyear Wrangler DuraTracs on it and the traction was amazing, even in 6 inches of snow. Hope the 2020 AT4 does likewise. Wish GMC had stayed with the DuraTracs.

I use The Fast Lane Truck guys all the time for reviews: Watch "How Efficient Is the New Chevy Silverado HD Gasser? Hint: There’s a HUGE Difference Towing & Not!" on YouTube https://youtu.be/vgniroEQ-Us

twofish I just put the Duratracs on my All Terrain two weeks ago, the Michelins were crap in snow. I drove over snow on U.S. 191 (8,000 ft) between Moab, UT and Rock Springs, WY; followed by on snow packed US 191 to Jackson, WY. We had many days of snow in Jackson, then on snow packed roads headed to Salt Lake City. I experienced almost no slippage, and stopping power was amazing. I'm a fan of the Duratracs for life.

Looks great, wished I lived in snow country so I could have a plow like that unit. Well, I could anyways, but not a lot of snow in Phoenix.

Great, I wondered about the timing of the CNET article. It was posted 21 hours ago.

Can't even take delivery once the dealer knows of this recall. CNET: 2019-2020 Chevy Silverado and GMC Sierra recalled for fire risk, stop sale issued. https://www.cnet.com/roadshow/news/chevy-silverado-gmc-sierra-recall-stop-sale-fire/

Yikes! 640,000 trucks affected. CNET: 2019-2020 Chevy Silverado and GMC Sierra recalled for fire risk, stop sale issued. https://www.cnet.com/roadshow/news/chevy-silverado-gmc-sierra-recall-stop-sale-fire/

And a safety recall just came for that truck, 640,000 trucks affected. Glad I haven't ordered a 2020 AT4 yet. Lucky your dealer let you take it.

When I bought my 2018 All Terrain HD I thought I had looked at all the numbers for towing so imagine my shock when I saw the payload max on the sticker on the door jamb of 2125. Only slightly higher than my 2012 Silverado 1500 with Max Tow. I had planned on getting a 2021 2500 HD. Working with the GMC configurator, the AT4 payload in my planned config is about 3450 lbs. Much better, so likely i will order a 2020 2500 AT4. But I might go with a 2020 3500 AT4. The new features are hard to ignore. Best of luck

The train wreck July 11th in Nevada may have something to do with the delays in shipments. Many GMC Sierras and Jeeps were damaged or destroyed. Maybe GM is using more semis to do shipments from the factory and there is a derth of truckers currently.

Length increased 3.4 inches, almost 1 inch wider.

It would be fun to put a 6.6 crate motor & 6 speed in my 2002 2500 HD 6.0. I thought about putting a 6.2 in the truck cuz I really enjoy the one in our 1500. After 110,000 miles including trailer I've had zero issues with the 6.2. But I'd think it kick azz to put headers, cold air (no such thing in Arizona) and a tune on the 6.6 to make the 2500 a sleeper.☺
