The Dodge doesn't get much better mpg than a full sized 3/4 or 1 ton Diesel truck does from what I was told, and the Nissan Titan with the cummins only averages 14 mpg not towing based on a test run article on it. But they are actually full size 1/2 ton trucks aren't they ? They do have more hp and torque but it's a trade off. And cost more $
