I'd definitely change mine for towing mirrors if I was hauling trailers more often.

Yah it’s an expensive upgrade for just looks haha

Definitely! Just looking at the 2020 build options on the GMC website, I think it was a $500 upgrade, or something like that.

Yah on my truck it would have only been $300 I believe, but on a LTZ it requires all of the safety packages, which would have increased my trucks price by $4550.  So I saved a ton of money just adding them my self.

Yes. I did get them working 100%. I posted in detail on the Facebook Group 2019+ Silverado/Sierra & 2020 HD Trucks. Here's the overview:

 

Here’s the circuits you have to tap into:
X4 pin 3 - right turn signal
X5 pin 2 - left turn signal
X7 pin 4 - cargo lamp LED’s
X4 pin 13 - running/clearance lamp

 

PM me and I will send you all the pics and procedures in detail.

    Hi I'm new to this blog. I have a 2020 RST Silverado 3.0 durmax. I forgot to order tow mirrors when I ordered my truck. I basically have manual folding, heated and power from the door with the standard mirrors that came on my truck. I located GM towing mirrors, # 84776100 from "shopchevyparts.com." Seemed to have best price $520 plus shipping to colorado $580.  Looks like they added turn signals, cargo backup to these mirrors, etc. Was told I need to order new wiring harness for the mirrors, which will be another $160. 

   Is it necessary to order these parts for both the Drivers and Passenger sides,  (84662371 and 84662372), or can I tap into circuits to avoid these harnesses. Appreciate any input.  Thx,  JB

You need both harnesses. Electrical for 2019 and 2020 is not the same, so I don't believe this thread will help you. You're mirrors aren't available for 2019 trucks because of the electrical system differences.

So question for you guys but in a different direction. My truck came with the tow mirrors and I do not like them. I do not tow enough to ever really use them. I want to move down to the standard mirrors. My current tow mirrors are manual fold, power adjustable, heated and have the task lighting. I have seen the standard size mirrors with the perimeter / task lighting, heated and power adjustable. Only difference is the lights are on the front of the mirror. Can I install them and everything work properly? Hope that makes sense! Thanks in advance for any advice on this!

I too have recently removed tow mirrors from my 2021 GMC Sierra that I would like to sell. Like New Pair of OEM Factory Power Folding, Manual Extending Tow Mirrors. They Have Work LIghts, Cornering Lights, 360 Degree Cameras, Blind Side Alert and Auto Dimming. Like New Condition.

I don’t seem to be able to pm anyone, I’m new to this site and maybe missing something in the settings. Anyway I’d be interested in your mirrors if still available. 
thanks

I have been debating on doing the swap to tow mirrors. We just bought a travel trailer to go camping, getting too old to sleep on an air mattress or ground. I have been going back and forth because I know I should get them but I hate the "dumbo ears" look. For now I am going with some snap on extensions since they are the cheapest option right now and I will get them before Memorial Day weekend for our maiden voyage in the trailer.

 

I was also thinking, once the truck is payed off, that I could somehow retrofit some K2 tow mirror instead. I know there would be body work on the doors besides wiring to get them to fit and work. I feel that they would look better however, just my opinion.

 

Here is the link to the snap on mirrors if anyone is interested.

I'm interested in buying your power folding tow mirrors. I have a 2021 RST 3.0 with no power folding option. Anyone know whats involved to make these work?

    • I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality. 
    • We had two Toyota’s with that engine in the mid 80s. We had 50 gallon fuel tanks, a toolbox full of tools, an air compressor and assorted parts for our equipment. We beat those up and down pipeline ROWs until we started buying diesel trucks. Then they became parts runners and first vehicles for our teenagers first cars. Our shop Forman wrecked them both two years apart when we hired him out of high school as an apprentice. Good thing he’s an excellent mechanic. It took awhile before he could be called a good driver.
    • I have a 2025 GMC Canyon Denali.   On a trip recently the engine failed.  The dealership diagnosed a bent valve and says there is a service bulletin that indicates to 'relace the engine'.  The truck only has about 14K miles and is under warranty.   The failure occurred 5/11/2026.   So far I have worked with GM Customer Assistance and Roadside Assistance.  Evidently no engines are available and nobody will offer a date when a new one will be.   Coming up on two months with no repair or timeline and no loaner from the dealership.   GMC Customer Assistance is 'ghosting' me and keeps closing the cases I've opened with no resolution.   Hoping someone can help me on how to escalate this issue.
