I am looking to upgrade to a newer truck I came across a 2 wd 2001 GMC sierra 2500HD. The bed is in bad shape no rust or accdents just scratches and scrapes etc.. and theres a few minor dents around the truck. its got 140k on the odometer and a 6.0 vortec V8. Now I know these trucks last ive personally seen them with 250k + on them, I do alot of towing as well. Is there any major problems the motors have? I dont really know much about the vortec engines or the previous matinence. and there asking 6,000 for the truck.
