Almost all reviews I have seen, mention that the fuel economy listed by the EPA is nowhere near what people are getting in real world. I have read people getting 18 to 19 MPG. I have ordered mine with Air Suspension which I guess adds more weight as well. Should I be concerned? The good fuel economy is what I liked and factored in while making my decision. Can you all share you thoughts about the fuel economy. Would love to see people share the real world numbers especially ones who have air suspension. Thanks in advance.
