Has anyone successfully been able to put tow mirrors on the 2019 Trailboss LT? Would really like to see some pictures if someone has and if they have does everything work as far as side marker lights and stuff? It's really annoying GM wouldn't have made tow mirrors available for 2019.

 

 

I believe Boost, mentioned upthread, makes tow mirrors for the 2019 and earlier trucks.  Just not the 2020 and newer models yet…. 
best of success to you.

I have been looking for the correct part numbers for the DQS towing mirrors for my 2020 High Country, @newdude helped me determine that 84994407 and 84879432 are the right part numbers for my truck.  It turns out that there are three different designs in 2020.

 

I found a set and ordered them today, hopefully all the standard features work.  I may have to remove the VCM, and have it reprogrammed to correct the camera angles and I'll need to determine how to correct the issue keeping the rear facing lights from working.

I have a 2019 RST. Installed Spec-D tow mirrors from Real Truck. Power adjust worked immediately, mirrors have heat option but my truck does not. The puddle lamps, reverse lamps, and amber marker lamps do not work. However, the marker lamps partially illuminate very dim at all times. They won't shut off on the truck until after several minutes of sitting.

 

I have seen the boost auto harness that supposedly connects the reverse lamps to your bed lamp button (which I have) but haven't attempted to purchase/install because I don't know if it works with non boost mirrors. Should I be considering GM harnesses instead to get the lights working. I've seen quite often there's a dramatic difference between 2019 and 2020+ wiring.

I think you need this harness to get all the functions working properly, with the RZY harness option for your 2019.

Big news!   Boost Auto Parts has released their tow mirrors for the 2019-2022 trucks.  Preorder available and 15% off with code EARLY2019. 
 

They have a good rep. I just ordered a set.  I hope they work as advertised.  🤞

Hey man. Does your high country have the tech package with 360 cameras, blind spot, etc? My ordered high country just showed up at the dealer with everything I wanted except tow mirrors. Wondering if you got this swap to work because I don’t want to wait another 10 months for a new build if I can order these mirrors and do the swap without losing any functionality. My dealership is telling me they cannot do it.

Believe it or not, the dealer has had my truck since I placed this order, so they aren’t installed.  I know there are issues to resolve during the installation.  Boost has the wiring mods that resolve the issues with spot lights not functioning and allowing them to work in reverse.  The VCM will need to get sent in to White’s (at least that is who I think it is) so the camera angles all display as they should.

Also, Boost has their own tow mirrors and the price per pair is much better than OEM…

Thanks for the reply. I looked into the boost option, however, they don’t support the 360 view with the cameras yet so I would lose that feature. Spoke with them and the camera compatibility is in development with no ETA.
 

My dealership is claiming there’s no way to get the GM DQS tow mirrors to properly communicate with the truck even though I’m trying to get them matched spec for spec (blind spot, cameras, etc) they say they cannot order those mirrors nor would they even connect. 
 

Has anyone successfully had their VCM reprogrammed to correct the camera angles?

Honestly, the dealer is clueless.  I would reach out to @newdudeto make sure you get the right part number for your truck and then hunt for the best price online.  Most of the features are plug and play with the right mirrors.  It is just the minor issues that you have to resolve. Also, mine is a 2020, I have no idea what the differences are on a 2023...

That’s kinda what I’m gathering. I’d reached out to him previously and he has been awesome answering questions and given me the part numbers. Huge help. 
 

The dealer has offered to cover the cost of the mirrors(before they said it couldn’t be done) so worst case I might just get them to order me the mirrors if they will pay for them and if they don’t want to try tackling the install I might try it myself. Have you received your mirrors yet? Or are they still in transit while your truck is at the dealer? Wondering if they really are plug and play or if there’s another harness I might need as some others have posted above. 
 

Seems like newdude is the community expert on this subject. 
 

If I could just order a new one and have it show up within a few months I’d do that but this one was ordered way back in January and is absolutely perfect aside from the mirrors. 6.2, max tow, tech package, multiflex tailgate, retractable steps, iridescent Pearl, nightshift blue interior. Very frustrating situation… doesn’t make it easier that when he said it was on its way I went ahead and bought rims, tires and lift which are sitting waiting to be installed. Should have known to wait for the truck to show up.

I have the OEM mirrors and the wiring mod kits from Boost sitting in my garage waiting to install.  I hope to have my truck back soon.  Boost has install videos, I think the install looks pretty easy.

Just got a reply from WAMS saying they have no workaround for the refreshed 22-23 trucks. Makes sense that with a totally new interior display that the VPM would be different from 2019-2022. Boost, however, is working on adding the 360 camera support on their mirrors, just with no ETA. Sounding like I’m going to be SOL if I take this truck until those new boost mirrors come out.

Got them installed...

 

Excellent quality and easy to install.  BAP has a very nicely detailed youtube video to walk you through it as well.

    • So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.
    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
