Beta Project is on a distinguished road

I just picked up a 2010 Ram 1500 Laramie with the 3.92 rear and I was originally worried about how my fuel mileage would be. I have only had it for 800 km's but in that period have averaged 13.8L/100km city and highway, far better than anticipated. I looked high and low for a truck with the 3.55 gears because I am on the road quite a bit for work. Definitley not dissappointed with the 3.92 gears and would be surprised if the 3.55 were that much better on fuel at all. The cylinder shutoff feature makes a huge difference and drops down to four at 120kmh. I am curious as to what numbers a 2010 with 3.55 is running... anyone?
