My 2017 Chevy 2500 Dmax was a lemon and went back to GM so I'm selling accessories I bought for it. I have a Lomax Hard Tri-fold Tonneau Cover ($750), WeatherTech floor liners ($100) and Du-Ha storage box ($150) that fits under the back seat and mates up to the rear floor liner. All were in use about 9 months and in good condition with all hardware. Some of these will fit other year / model vehicles. $900 for all of it.
