In part you're doing better than I. With my crew cab/long bed/3500 DRW with 4.10 gears - I have gotten between 8.5 - 11.0 mpg towing. My towing speed is typically 62-64 mph on highways.
Unloaded, around town and highway miles mixed it, I'm usually getting between 10 and 14.9 mpg. My non-towing speed is typically 7-9mph over the posted speed limit on highways and 3-5mph over the posted speed limit on secondary roads.
Towing-wise: I generally pull on highways up and down the east coast. My fifth wheel weighs right about 14,000 pounds. The truck, fully loaded (including pin weight) comes in right about 11,500-12,000 depending on who is with us and what the trip consists of.
I'll be honest, I had hoped for better mileage too.
