GMC's all-new 2020Sierra Heavy Duty will feature more room and amazing towing capabilities. “The all-new 2020 Sierra HD is the most capable heavy-duty truck that we’ve ever offered,” said Duncan Aldred, vice president of Global GMC. “For customers who demand a premium, innovative heavy-duty truck that supports their passions, the next-generation Sierra HD can pull like a pro.”

There is a lot of new and notable capabilities in the 2020 Sierra HD, so we are breaking down the key elements into bullet points.

Here are the 2020 Sierra HD general features. Trailering features come below:

A segment-exclusive available 15-inch-diagonal head-up display that offers useful trailering information, including vehicle speed, navigation information and an inclinometer display for the road grade.
An available segment-first Rear Camera Mirror.
MultiPro, the world’s first six-function tailgate, allows easier loading, unloading and bed access and is available on all trim levels.
A larger, commanding design that provides more room for cargo and occupants.
Best-in-class Crew Cab front headroom and legroom for the driver and other front-row occupants.
An all-new, segment-first, Allison 10-speed automatic transmission mated to the legendary 6.6L Duramax turbo diesel.

2020 Sierra HD Advantages Over Prior Model Include:

A longer wheelbase, a taller, more dominant hood line and taller overall height.
A larger grille and complementing functional hood scoop to feed an advanced cooling system for the Duramax turbo diesel. 
Class-leading heavy-duty cargo bed volume and corner tie-downs with a new, available 120-volt power outlet.
One-inch-lower bed lift-in height compared to the 2019 Sierra Heavy Duty, providing easier loading and fifth-wheel and gooseneck trailer hitching.
New, segment-exclusive cargo bed side steps on all box styles, located in front of the rear wheel openings, that complement integrated CornerSteps in the rear bumper to improve access to the cargo area.
World’s first six-function MultiPro tailgate available on all trim levels and standard on SLT, AT4 and Denali.

 

GMC’s Duramax turbo diesel and new 10-speed Allison automatic transmission pairing will offer superior towing confidence. GMC isn't providing exact specs today, but says that the 2020 Sierra HD will have capabilities well in excess of 30,000 pounds. This is the first HD segment 10-speed. The Duramax 6.6L turbo-diesel engine develops an SAE-certified 445 horsepower and 910 lb-ft of torque.

An available smart trailer designed to integrate the iN∙Command control system from ASA Electronics provides the ability to monitor and control select functions of compatibly equipped trailers through the myGMC mobile app.

Auto Electric Park Brake to automatically apply the parking brake to help maintain truck position when hitching.
All-new Park Grade Hold Assist enhances hill hold by using braking effort at each wheel for an extended period of time.
All-new larger, door-mounted trailering mirrors with a four-bar link providing power extend and retract for the driver and passenger sides.

Hill Start Assist and Hill Descent Control.
Trailer Sway Control.
Auto Grade Braking and Diesel Exhaust Braking.
Digital Variable Steering Assist that dynamically optimizes power steering according to driving scenarios, including trailering, and enables features like road pull compensation.
Trailering Info Label placed on the driver’s door jamb that clearly calls out the truck’s specific trailering information, including curb weight, GVWR, GCWR, maximum payload, maximum tongue weight and rear GAWR.

I agree, for the first time ever I like GMC's front end way more than Chevy. They sure ruined that. I'm so glad I got mine in 2015.

Love my 2018, but can see why some might opt for the 2020.  GMC headed in the right direction!  Lots of smart and cool options. Good looking truck.

Funny, you think they will stop production because of you? 

Personally, I like the 1/2 GMC over the Chevy.  But on the HD class, the Chevy looks far better.  Looks like it means business.

I', sorry, but these are fuglier than sin! The new RAM trucks look a hell of a lot better and offer way more than anything GMC and Chevy are offering - and I currently own 2 Sierras.

After the issues with my 2016 gmc all terrain pickup I'll never buy another gmc or Chevy product.   Paint issues from the factory that they'r factory said wasn't from them and the dealership says isn't from them.   Then shocks going at 35000 miles along with airbag issues, backup sensor issues,  electric mirror issues and many more.   Your trucks are shit!!!

I have a '16 Denali dually. I hope they (2020) model fixes before its maiden release. The charging cell phone arm rest to actually be stronger and allow phones with cases that FIT the opening. Also those camper mirrors to be about 2 inches wider when open and have defrost. Fix camera issues that when reversing and pulling foward you have to re-enter your camera set up (yes I have the same cameras from Rostra). the overhead view is good for only 32 feet trailer and NO goose neck or 5ther!!! REALLY! Most serious dually users are over 32 feet. Why have all that GVWR if ur under 32 feet! Better get that distances expanded. Also that overhead view add a zoom while backing for the last 12 feet of the rear of the trailer for close objects... gas pumps, mail boxes... walls etc. 

I am on their email list and I await some of these answers. Also why no radio on the drop tail gate for the dually, we also do go events that could use it.

      I have a 2013 GMC Sierra 1500 SLT that I just bought and I am looking to hookup an after market subwoofer and amp but I like the stock dash look so I don't want to replace the stock radio (which would make this process a lot easier). Would I just replace the stock sub and amp and splice into the current wires? Could I keep the stock sub and amp also while connecting new sub and amp? Does the stock radio have RCA connectors in the back that I can connect too?
       
      In a perfect world I would be able to add a new sub and amp without replacing the stock sub and amp and still have a high quality sound system without using RCA plugs since I do not think they come on the back of the stock radio.

      Hello Everyone,
       
      I have been looking at adding a couple of cameras to my 2019 GMC Sierra 2500HD Denali.  These trucks can be difficult to pull into parking spaces and lots, especially if they are smaller.  I just recently raised the front end about 2-3 inches, this has made parking a even bigger challenge.    Yes, when parking I try to back into most of the parking spaces, but sometimes that option isn't available.
       
      The system I have been looking at is from Echomaster, this system is listed under GM accessories and is labeled Intellihaul.  The multi-camera system comes complete with a interface module, wiring, two (2) cameras that are mounted within a black mirror trim piece that attaches to the bottom of the mirror.  The trim level on my Denali comes with trailer towing mirrors that are all chrome, and I really didn't want to substitute the lower black trim pieces in place of the chrome.   I have seen one and it didn't look that good, on the all black mirrors they look OK (Just my preference). 
       
      Echomaster has just recently released a new 3rd brake lamp camera that has three (3) different viewing angles within a single camera,  a right 95 degree,  a left 95 degree and a rear 90 degree.  Then all I would have to do is add the front facing camera.  In this arrangment, I would have to utilize a multi-camera module, this module is complete with wiring harness, bracket and OEM interface jumper cable.  However, the new released 3rd brake lamp camera only has one (1) video output.  I would have to hard wire 3 more input triggers to make this function correctly, the left and right turn signals and reverse triggers.  To operate on the OEM radio screen, I would have to depress the "back" button for three (3) seconds until the camera icons appeared on the screen. This would give me the rear cargo area.   To view both the blind spot camera views, I would have to cycle the left or right turn signal depending on which camera I want to view.  I would also have a front facing camera installed in the grill area, which would assist in parking manuevers.  In this setup, I still would have full operation of the OEM backup camera when in reverse.  I think this would be a good option and give me what I was looking for. 
       
      When I talked to the tech assistance at GM this afternoon, he said that the system would be awkward to operate. I would like something that is plug-n-play, a system that I didn't have to rely on to take to dealer to program the radio, BCM or any other related modules. 
       
      What is everyone doing about adding cameras to your truck, what sytem and options have you looked at and/or are utilizing?
       
      Do you like your truck with the camera addition? 
       
      What are your thoughts?      
       
      Thanks,

      GM has available now factory camper mirrors!  Time for a nice run down on them and what is involved. 
       
      What they are:  Factory tow mirrors.  https://accessories.chevrolet.com/product/extended-view-tow-mirrors-in-black-84731241?year=2020&make=Chevrolet&model=Silverado%201500&categoryId=98023
       
      Price? Part #?  84731241 is the #, MSRP for the mirror package is $730. 
       
      What do they feature?  Includes lower convex spotter glass, as well as cargo lamps, clearance lamps and integrated turn signal indicator.  Manual extend and manual fold.
       
      The good:
       
      -GM has factory tow mirrors available as an accessory for trucks that don't have them!
       
      The bad:
       
      - 2020+up ONLY at the moment.  They do NOT list them for 2019.
      - They DO REQUIRE HARNESS SWAPS.  Both front doors require new door harnesses.
      - If you have the front spotter lights in the mirrors or have blind spot alert, THESE WILL NOT WORK! 
      - BCM calibration required for ALL models to make all lighting function. 
       
      If you have the dealer do it, its about 3.6 hours. 
       
      Harness numbers will be listed below:
       
      2020-2021 Crew and Double Cab with KEYED ignition and DLF mirror:  84622369 and 84622370
       
      2020-2021 Regular Cab with KEYED ignition and DLF mirror:  84622376 and 84622380
       
      2020-2021 Crew and Double Cab with PUSH BUTTON ignition and DLF mirror: 84622371 and 84622372

      I have an aftermarket stereo in my 2006 GMC Sierra 2500HD with the Bose sound system. Currently, i only have one speaker working, the other 3 have no sound coming from them. Any idea what could cause this? or a work around for the Bose system. Im tired of listening to my music through one speaker.

      Hi all.
       
      Looking for a single down-fire sub-woofer enclosure for a 2019 Sierra Crew Cab, new body style.  Any tips on where to find this?
       
      Thanks!
