Stop in for a cup of coffee

I bought a new 79 150 Club Cab 360 2 wheel drive. It got 12 mpg empty or loaded
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
