4.10. Love it. - - - Updated - - - This is my rig towing the beast of a trailer. My wife towed it two days ago (finally got her to try it), and her comment was "Wow! This is SO much easier than the Expedition towing that 19' trailer!" NO kidding. Love those dual cams... The power is nice, too. Just toss it in 2nd gear and go up and down the mountains all day long without shifting. This last trip, I got 8.9 MPG, but it included the nastiest grade within 200 miles. Up and down I went with the flow of traffic... the CAR traffic. I just chuckle when I, at 60-65 MPH, pass those big diesels running at 40MPH up that hill. The picture is deceiving too. I actually still have quite a bit of play in the rear suspension. I've thought about timbrens, but the ride stabilizer button works wonders if any bouncing starts. Every time I drive this truck, I'm ticked to death to have gotten so lucky to have found it. Blessed even.
