I have a 2004 GMC Duramax. Its got high miles but still has plenty of life. Has a B&W hide away gooseneck ball. Four wheel drive. 4 door. 5 speed automatic Allison trans. Short bed. Has 16 inch Pacer rims with maxxis mudder buckshots tires with 40% tread. Never turned a wrench on it except an alternator. I serviced it every 3000 miles. Im the 2nd owner. Been a great truck! Nothing bad to say bout it. I could consider trade to a 99-06 dodge 4x4 flatbed. prefer 6 spd but 5 is alrite. Prefer a regular cab but 4 door be fine with a flat. You can reach me by email or call. My cell is 606-278-2209.
