Mine is a 4x4. I've heard about the oil burning problems with the 07 from other people as well. Another thing to increase mileage is to switch from the stock clutch fan setup to the newer (I think 2005 and up) electric fan and radiator. I heard it can help pick up 1-1.5 mpg but it's not the easiest/inexpensive upgrade so I haven't done it yet. My truck is actually pretty loaded with power seats, power windows, power windows, etc. which is a little odd for a reg cab pickup. The other thing that is actually cool about getting a programmer is that with the automatic with the tow/haul mode you can give it 2 different tunes and use the tow/haul mode for better performance at just the touch of the button.
