Hello.......i currently have a 2003 Nissan Xterra XE 4x4 that is paid off, i would be trading it in...........im thinking about upgrading to a Titan 4x4 king or crew cab (used, 04-06) in a few months, just trying do some research first........my current mpg is pretty low but i think its the big tires and slight lift..........i took a road trip this weekend and only got a touch over 13mpg averaging about 75mph.........if i decide to get a Titan (will be staying stock except maybe an exhaust) would it be safe to say that the mileage will be the same or slightly better with mixed driving? Im also considering the Frontier but i really want the bigger sized truck.........

Thanks,
Robb
