ordering 2020 Sierra with max tow

flattop · February 20, 2020

Hi Folks,

I am having trouble on the GMC website trying to build a Sierra 1500 SLT 4X4. I have a base model SLT with the 6.2 and the 10 speed, and the Max Tow package configured. The problem is nowhere is there the option to add the trailer mirrors? This configuration also allows the 18" rims and the 2 speed transfer case to stay on the order? I like that!

Just throwing it out there to see if anyone has ordered a 2020 SLT with max tow and got the trailer mirrors?

My salesman is on vacation this week, so I will have to wait to consult the dealer.

Thanks,

Flattop

Tow mirrors on 1500 weren't available in 2019. They returned in 2020.

Tow mirrors are no longer part of the Max Tow package.

Tow mirrors can be added to any trim -- even thou max tow cannot.

The diesel can't be ordered with max tow - but, for example, you can order a diesel Denali with tow mirrors....

However, you can't find them because on SLT, tow mirrors are no longer available to order for 2020.

Here's from the current order guide for 1500 Sierra:

DQS NEW! Mirrors, outside power-adjustable vertical trailering with heated and auto-dimming upper glass, lower convex mirrors, turn signal indicators, puddle lamps, perimeter lighting, auxiliary lighting and memory; power folding/ manual extending

On SLT - No longer available for 2020. Requires (CWM) Technology Package.

On AT4 - Requires (CWM) Technology Package. Not available with (S4X) Black mirror caps, LPO.

For the other trims:

DPO NEW! Mirrors, outside power-adjustable vertical trailering with heated upper glass, lower convex mirrors, integrated turn signals, clearance lamps and auxiliary lighting; manual folding/extending

On Base Sierra - Requires (PCI) Convenience Package or (PEB) Sierra Value Package and (Z82) Trailering Package. Includes (DD8) auto-dimming inside rear view mirror. Not available with (ZW9) pickup bed delete.

On SLE and Elevation - Includes (DD8) auto-dimming inside rear view mirror. Requires (Z82) Trailering Package.

Max Tow is only available on SLE, Elevation and SLT.

Max Trailering Package, includes 9.76" rear axle, (GU6) 3.42 axle ratio, enhanced cooling radiator, revised shock tuning for increased control, heavier duty rear springs, increased RGAWR and (KW5) 220-amp alternator

GMC does not offer tow mirrors on SLT models. The reason is that they only offer power folding tow mirrors with cameras on them, which requires the Tech package. Tech package is not available for SLT models.

You have 2 options to get tow mirrors on a GMC, and only the first lets you keep a 6.2: 1) Step up to a AT4/Denali to get power folding mirrors. 2) Step down to a SLE/Elevation to get manual folding mirrors.

SLT got the shaft in this generation. An LTZ or High Country will build out to exactly what your looking for. If you insist on 18” wheels, you’d have to stick to the LTZ.

Thanks for the replies, I guess I could just order the SLT and then order the towing mirrors and install them myself. Seems really strange to offer the Max Tow package ( for towing large heavy trailers) and not offer the large towing mirrors?

If the 6.2 was an option for the SLE max tow, i would go that route. I don't want leather or the other SLT options, just a 6.2.

Must be some sort of production quantity issue.

Perhaps more volume being ordered than they planned and tooled to produce?

Anyway, the guide entries for the CWM technology package and the DQS power fold tow mirrors both have notes that they are " No longer available for 2020 " .

Seems like the were available -- so there may be still some out there at dealers.

Are you dead set on a GMC? You can get a Chevy RST 6.2 with Max tow and manual folding trailer mirrors. You can keep it pretty plain with 18s and cloth interior, as a matter of fact I just built one with the only options being those 3 things, keeps it pretty cheap. If it were me ordering the truck I would definitely add the All Star package to get some creature comforts, but that's optional.

RST won't have all the fancy trailering camera views -- if you are interested in them.

Awesome man, hope that helps!

If you add advanced trailering I think you get those, don't you? What's missing?

No that wont be a show stopper. I have a 17 Silverado 1500 with the Max Tow package currently. It has no fancy cameras, simply good gearing (3:73) and the nice mirrors that help with towing the camper.
