Taking the truck in for the second service. Build date was February 2013. Truck has 10k miles. Other than it has water dripping from (2) certain hinge points in the exhaust system I have had 0 issues. Getting 17.8 on last fill up. Full Mobil 1 synthetic going in. Thats about it. Anything else I should have looked at? It does have a level kit, and 33's on XD Wheels. I will rotate and balance as well.
