Recently broke-in my 6.2 with a 10 speed. I found the truck liked to run 1300-1500 rpm. Around town driving I could hit 3500 rpms at a stop light, but that quickly gets you to the speed limit. Then 1300-1500 rpms. Even on the highway, 75-80 mph would only get me to 1800 rpm. I found running in tow mode would vary the rpms 1500-2500 rpms, 3500-4500 at takeoff. Sport mode was not as effective at varying the rpms. Note: I always disable the auto engine shutoff.

I really like the look. Where did you buy the paint?

Same color as my truck. I was debating color match or black on the fog light trim. Please post a pick when you get them back on.

What color is that, looks good

My MX4 came with the larger rubber blocks and separate instructions to install on 2019/2020 GMC/Chevy. With the rubber blocks, it rests on the back window.

https://www.gmsupplierdiscount.com/build-and-price/ You can go to the GM Supplier Discount website, build the exact vehicle on the lot. (Does not work on a mobile device, Only works on a computer). Will give you a pretty good estimate of a good price. Somewhere between that price and MSRP, but who knows, you may be able to negotiate a better price.

Very well done! That’s a tough looking truck
