Hi again,
Narrowing my search.
Looking at two 2006 crew cab sierra 1500. One I think is an HD (searching on line). both are 5.3. one has 3.73 ratio and the other 4.10. The one with 4.10 has a Vortec Max. What kind of mileage difference if any. Any idea what kind of mileage I can expect without pulling. I may pull our trailer 4-5X a year.
Thanks for you help. Your info has been great.
