2007 GMC 6500 7.8 turbo diesel with allision automatic 270,000 miles runs good and is in great shape, you wont find any with a rust free cap like this one. I bought it to make a dump truck but to many projects. It was an old beer truck so they had the frame cut out and reinforced but that has been filled back in with new metal, would make a great dump or service truck. call with any questions $7700 CASH ONLY!
