Stop in for a cup of coffee

Depends what you call bad gas mileage. My Jeep Grand Cherokee would get 15 MPG towing a 10' trailer loaded to the hilt with motorcycles and 19 around town. ANd the 4.7 is the easiest engine to work on until you come to the timing chains
Have a "maybe" rig out in Greensburg, PA.... Might make a run up.
