What kind of fuel mileage can you expect

My 12 Ram 2500 CC LB 4x4 3.73 averages about 11.5 in town. I don't baby it either. On the hwy 55-60 mph about 18-19 mpg. On the freeway running 70 mph about 17mpg. Towing a 9000lb 28' 5'er it gets between 10.5 and 12.6. Last 400 mile trip which included a climb up to 5000' from 132' (home), 75 miles of solo driving and back down to 132' I got 12.6 for the whole trip. Normal seems to be around 10.5-11mpg towing. I don't drive slow either. I could easily get another 1-2 mpg if I slowed down.
