I'm new here. I got the 2023 AT4 with the small diesel. Mileage is amazing. I have the Carbon Pro short bed. Discovering that there are fitment issues with some of the bed accessories I am considering. I did replace the OEM rear under seat storage with a Rough Country version and my bug out bag fits now. Worth $100. I also added 2" spacers to the 20" wheels. Made a big difference on the look... in my opinion. I'll probably replace the wheels eventually, but for the duration of the stock tread, it looks good. The only other thing I have done so far is add a tailgate anti-theft device. $40 seemed like cheap insurance.
