2006 3500 Dually Towing MPG??

I used to have a 2006 3500 4x4 6 spd manual dually and I seem to remember getting 14 mpg towing 15,000 lb trailers. Does this seem right or am I smoking crack.

Reason I ask is I'm thinking about getting rid of my dmax and going back to an 06 dodge. I went to an 09 dmax after my 6.7 dodge left me stranded numerous times. I love the dmax and have it the way I want it but I tow a 3 horse trailer with a 13' living quarters and slide out and the best mileage I can get is 10 mpg. An extra 120 miles per tank would be worth it to me. I have my on an 06 with 50,000 miles on it.

What are you guys with the 06's seeing for mpg towing heavy loads.

I have an 03, the weight I pull varies but it's usually around 8-10k lbs (not including the weight of the truck). I usually drive 60-62mph and I get from 14-17mpg depending on wind and hills.
