I love the blade silver colour from the photos I've seen. I would go for the 1LT, no Z51 or NPP. The after market may be ripe to turn this beast into a super beast.... or I may wait for the next higher output model. A 5.5 flat crank would be nice, with about 600 hp.
To be determined.
I've got the rear camera mirror in my 2019 Sierra. I see it's an option with the 2lt along with power folding side mirrors.
Great Expanded Peripheral View that takes a bit to get used to when doing a quick rear view glance in camera mode.
Hopefully it has a turn-on camera and turn-off normal mirror method like my truck as sometimes the camera peripheral
can get your attention when not needed.
I like the driver & passenger seat memory too with the 2LT and above
