GMC SIERRA 2500HD 6.6 Duramax Diesel

This is a good truck that needs some work. Has some clear coat peel on box and has some rust on lower left cab corner and scratch on tailgate. I drive truck everyday but when you fill coolant resovoir it pushes some out but Temps stay where they should be even on steep hills. Could be head gasket. New water pump last year, belt and idler pulley. Truck runs very strong. Get about 18-19 mpg on highway. Tranny perfect. Heater and air cond. perfect. Has tow package with electric brake setup. I can deliver this truck for free if within 250miles of zip 18255 further than that will talk about it. Truck is ready to work just add antifreeze once in awhile or fix. Spray on Rhino liner in box. Email all questions. Thanks
