Bought this truck at 300,000 miles with a cracked radiator. Only real maintenance done to this truck is a new radiator, new alternator, one new coil pack,
and some gaskets and seals. Before we started playing around with it it got about 17 city 20-25 highway. After putting a 2.5 inch suspension and 2.5 inch body lift its down to about 10 city and 15-17 highway. Mine is actually the 5.4L Triton V8. Soon the driver side A-frame will need replacing and the passenger side rotor needs to be replaced.
