Chevy 3500 express box truck

2006 chevy express 3500, 10ft box truck with 6.0 gas engine. Truck was bought new and used locally to sevice fire extinguishers until it was replaced. Has had several new parts installed including starter, water pump, brakes, and roters. The truck starts and runs HOWEVER it does need a new oil pump, the engine developed a ticking sound coming from a lifter. The truck was taken to a mechanic who put a mechanical oil pressure gage on the engine and stated it was getting very low pressure due to bad oil pump or clogged oil pick up tube. The truck was parked and replaced, approximate estimate to repair is 1200-1500 dollars. ALSO NOTE the shelving, tables, inverter, and battery does not come with the truck. If you are interested in buying it with the truck it will be 1000.00 more, a very good deal considering the inverter alone is worth that. No low ball offers replied to. Also paint on the hood has come off primer is still intact chevy had an issue with paint primer bonding on this year truck.
