Looking at the base Pro trim, you will find that it comes with hitch guidance. Being that it starts on the base trim, you will find it across the lineup. This helps backing up to a trailer easier than before, never having to readjust more than once. When needing to get into the bed, you no longer have to take large steps to get in thanks to the CornerStep feature that will come standard on all trims.
The Denali Trim
The Denali makes driving and riding in the Sierra HD much more comfortable. When in the front row you will be able to enjoy heated seats, making even the coldest days more comfortable. When the weather starts to get warmer, the ventilating features will make sure you’re cool. While this truck does come with comfort features, it doesn’t sacrifice what it means to be a truck.
The bed of a Denali comes with a spray-on bed liner, it not only helps keep things from slipping around, it also keeps the bed safe. If the CornerStep bumper isn’t enough, you will find that the MultiPro tailgate will surely steal the show. Instead of having to use a small step on either side of the tailgate, you will be able to flip out a step from the tailgate, giving you more room to get in.
The AT4X Trim
The AT4X is exclusive to the 2500. This trim comes with the MultiPro audio system. This system operates independently from the interior system allowing you to enjoy music no matter where you are. To help you get in and out of the truck, the power-retractable assist steps will be sure to do their job. When not in use these steps will go back up, keeping a slick look.
