Having owned the truck for about 2-3 weeks, I've gotten black bow ties put on, a spay on bedliner (free from dealer as we negotiated this), added the Bakflip MX4 tonneau, and bought front/rear Weathertech floor mats.
I do want to add a CAI next (thinking between GM or Flowmaster) and have spoken with pgamboa about getting the DL3 mirrors/harnesses. I really want the turn signal blinkers, just stinks that the blind spot sensors weren't added till the 2019's.
Then hoping next year I can get a different exhaust installed and possibly either good quality seat covers or researching getting leather upholstery for my cloth seats. My kids will find ways to get some food or spill on these seats. LOL!
Sometimes I feel like I should of sprung for the LTZ, it would have had some of these things right out the gate that I want to do to my current truck. Guess will be the next go around down the road.
