2019 GMC Sierra 2500 HD, 4x4, long box pickup truck

I have owned this truck for the last several years and it served me well pulling my fifth wheel RV. Since my wife passed I have sold the trailer and now would like to sell my truck. Here are a few features included: backup camera, folding mirrors, running boards, Back Rack, complete fifth wheel set up, 2" trailer hitch and leaf spring all around for stability with extra heavy loads. There happens to be a small dent in the front bumper and the module that controls the audio and a few other functions needs replacing at a cost of $1,000. as quoted by GM dealer.
