2004 Silverado work truck with tool box and ladder rack

2004 Silverado with 189,000 miles. $3,200 OBO Includes Weather Guard ladder rack and aluminum tool box (with key) Was my daily driver until new truck purchased. Recent work by local certified mechanic (receipts available): rear brake pads, rotors and calipers $380 exhaust system $500 starter $300 Catalytic converters replaced in 10/2015 $853 Instrument cluster changed in 2/2016 $695 We Okole seat covers $300 Truck needs a new timing cover at some point. Drips some oil but runs good. Mechanic says this is common issue with this truck as plastic covers from manufacturer. Also has a sending unit that acts up in fuel tank when truck is full - gas gauge reads odd until fuel gets lower in tank.
