This model truck has an aluminum frame with steel parts bolted to it. The only thing wrong with it is in the points where steel and aluminum meet there is oxidation on the aluminum. We stopped driving it for fear of the frame giving us trouble in those places. if someone were to scab across the frame to strengthen it, it would be a very great and reliable truck. You can't find a CAT engine and eaton transmission combo for this price. They are both in phenomenal shape and so are the tires and rear ends. Bottom line, the parts on this truck are worth more than I am asking. if you have any questions or would like to test drive give me a call.-Andy $10500, 2704331290
