Towing mirrors

[AT4 TV]

Looking to upgrade my mirrors to tow mirrors. Has anyone seen any options for the 1500 AT4?

I saw this one but when I called the dealer parts department, they said these are not compatible for 2021 AT4. They said to check back in a few months.

Dealer said my truck is DEZ-RPO and these mirrors are only compatible with DLF-RPO.

What bed length and engine do you have?

Short box and 6.2L.

Short box and 6.2L.

Thanks. These are the same ones that Lambo posted, but from GMC Accessories. When entering your AT4, it says they WILL fit. I would go ahead and order them (probably from Lambo's link, because of the discount), and if they don't fit, there is no reason for GM not to give you a refund/free return as their website did say these will work.

The incredibly long link

Good luck, and thanks to Lambo for the part number.

Thank you Lambo and Dullies. Will call dealership to get some quotes on the install.

Doesn't look like a very hard installation, might want to attempt yourself instead of taking it to the dealership

Installation video (has links to wiring videos in description, not sure if you would need them or not):

Do you know the part number for the door wiring harness that is required with these? Will try to call them tomorrow

Can’t wait to see them installed!

Didn't see this before, do you have either of these?
