I have a lifted 4x4 1988 Suburban with a 6.2 diesel. It gets amazing mileage for that size of truck, 15-20 MPG depending on conditions. I do run Diesel Kleen and Stanadyne fuel additives every 3rd time I fill up; supposedly that helps mileage too. Either way, the Suburban is an amazing truck; practical, reliable, simple to fix, and built like a tank.
