I am selling my 2007 GMC C5500 Topkick dump truck. It has 96750 miles. It has the 6. 6L Duramax with Allison transmission. New front tires. new injectors. new driveshaft hanger bearings. new alternator. rebuilt rear end. etc. I can provide a full list of work upon request. It is literally in perfect running order. there is nothing left to go wrong with this truck. The box is a little rusty. the truck body has a few small spots under the doors. a tear in the drivers seat. otherwise totally clean. It has a 14ft dump box. a tailgate with two grain shoots. and a stainless steel Swenson salt sanding gate. Everything works. the box could use some work. or replace it with a new one. The lift is in excellent shape. It runs good. starts easy. drives nice (for a truck that size).
