New to the forum. Coming up on 2 years of ownership of my 21 LT trail boss. 15,850 miles. In that 2 years, replaced dealer installed running boards with Westin HDX, blacked out the tail gate letters and silverado LT badges, blacked out the Z71 badges, tinted the front windows, put on retractable bed cover from GM accessories, added weather tech rain guards, replaced factory trail boss decals with a more clean looking black decal. In the last week, my wife for Christmas got the hood "buldge" wrapped and the GM accessories Nudge bar installed. Future upgraded will be black lug nuts and to replace the fake wood inserts on the interior. We will see where we go from there. At the moment, it is the family truckster so I will probably stay pretty stock on the wheels and tires.
