2007 pre DEF Duramax! I just put some needed work into this to get it reliable and solid so my son can drive it now that he’s 16 but honestly, fuel is to expensive for him to drive around so decided to sell it instead! Just put new batteries in, new front end work, and new tires. It’s been a great strong truck just have no need for it. I’ve had it since 2019 and was my main vehicle until end of 2023. Then It was a loaner truck for family who needed a vehicle for about a year and a half and just got it back. I’ve never towed anything with it, but I’m sure previous owners have. Feel free to call or text for more info or pics. $18,000 OBO
