Regarding options for steps, our 2015 Silverado came with the step option. To make it easier to get in and out, I had the AMP Research Power Steps installed. They made getting in/out MUCH easier as they are 4 inches lower than the factory steps.
I only wish the truck didn't have the $600 factory steps as I am also having trouble selling them. (The AMP Research Power Steps were $1300 plus $300 for installation. Well worth every penny!)
