I own a 2019 next gen sierra (elevation) and I'd like to install the extended view tow mirrors (part # 84776098). My truck is equipped with DLF and not UKC as specified in the part description. GM says these mirrors will not work on my truck …. GM enthusiasts. Is this true? I feel like it's bullshit and the harnesses are plug and play? If they're not plug and play, is there an alternate harness? It can't be possible that this 1/2yr model can't be equipped with tow mirrors? Help please …..
