I don't use the truck. Haven't had anything in the bed that has liner and folding cover. I change oil every 3,500 miles. No one uses the back seats because don't have children. I get 19 miles per gallon at 1,700 rpm at 80 mph. I just replaced all 4 tires costing $1,000. Replaced all 16 spark plugs and wires and all for brakes. The spares has about 200 miles on it
