hey guys I just purchased a 2007 dodge with the 6.7. Beautiful truck. It's got a lift and 37 inch tires on it... anyways I'm getting Edit gas milage even worse when I pull my trailer. This weekend I got 6.8-6.9 mpg's... it has an edge turner (older model)... any reason why I'm getting such bad gas milage when I have friends getting twice as much? I recently added a new fuel filter and cleaned out my air filter... any help is appreciated! Thanks in advance...

As stated more info would yield better help. Anytime you install big tires, and especially not change your axle ratio to get your mph back with your engine rpm range your mileage will suffer greatly.
