Finally got my 2021 At4 yesterday. Had to drive 400 miles to go to a dealership that just got one in. 6.2L, carbon pro with the technology package. Awesome truck!

I got my 2021 AT4 July the 8th and after looking on here you guys cost me a lot more money. 
 

I’ve tinted the windows, taillights, side part of headlights, fog lights and the blinker on the mirrors , plasti dipped the GMC logos and the AT part of the AT4, debadged sierra off back tailgate, bought the center storage kit off Amazon, put a flow master 40 serious on and cut off the flapper, it’s getting the ceramic coat as we speak, getting 305/55 R20 MTs put on Saturday, ordered Lund rock rails with rampage short steps (best looking nerf bars in my opinion).

 

Wife’s not to happy on my spending lol. So once the heats off me I’ll buy and S & B cold air intake and an RC 2” level kit. I talked to RC today and they stated you do not need to change out the UCAs with their kit. Most others you do, but RC said they designed them this way.

Had the dealership install the hard folding tonneau cover for the carbon pro bed. Fantastic fit and finish. The only other thing I did was install vinyl carbon fiber wrap to cover the chrome interior pieces. Be gentle I know it is not perfect but it is the first time I have ever tried vinyl wrap. Not horrible for a rookie.

Just had ceramic tint installed today. 70% nano ceramic on the windshield, and 15% nano ceramic all the way around. Quite a surprise when I got the bill but if ceramic lives up to what I have read about it then it will all be worth it.

Ceramic is the way to go!  Have it on my Camaro, and just had it done on my AT4.  It does block a lot of heat. 
 

I personally don’t do the windshield - my luck has been I’ll catch a big rock, etc, the next week or month and have to replace it anyway.  So I just do a dark “eyebrow” across the top, and then use a sunshade when I have to park it out in the sun.

[RCF71]

Bought a 2021 AT4 with the 6.2L a couple of weeks back, pretty basic - only options were the 6.2L, Satin Steel paint (wanted this or white, and this one was on the lot), Duratracs (on 18” wheels), and the tailgate speakers.  Oh, and NO AutoStop/Start!  I was wanting more features, but honestly now I am actually pretty happy that it didn’t have more - every package had some stuff I wanted and other stuff I didn’t (did not want sunroof, sliding back glass, lane assist, navigation, etc).  Only requirements I had were 6.2L, cooled seats (standard anyway), and white or grey.  I’ll add/modify other things I wanted.
 

I picked up a set of the AT4 high clearance steps a week later, and then had Ceramic tint installed all around (just an “eyebrow” on the front).

 

Looking for a tonneau, had a roll n lock on my F150 but trying to keep cost down on this truck.  Found a like new Rev (GM accessory), will likely buy that as I can get it for a great price.  Then I will probably buy the full Kicker upgrade (amp for speakers and amp/sub) and change out the factory speakers.  Also would like to take out about half of the factory rake, so may add 1/2-1” spacer in the future.  When these Duratracs wear out, will probably consider buying some 20” wheels and tires.

 

Seeing all the custom badges here has the wheels turning too!  Haha!  Maybe a mix of US and TX flag designs... hmmmm!

Added bed bars.

Added RC 6" Slim LED light bars to the grill. They blend into the grill very nicely. Also added a diode for the fog lights to come on with the high beams. I like to see at night when I'm out on the frozen lakes ice fishing.

They are plasti-dipped, then pealed the red centers of the "4's".
