I haven't towed with one but I think expecting 10-11 towing is very optimistic. Fuelly says the average MPG is a little under 12, which would include towing and not. I think Fuelly tends to be pretty close to real world. I'd probably bank on most folks getting more like 8 towing. Obviously driving habits play a big role.

The downside of Fuelly is that you don't know how much is towing or even what type of towing. I would bet that in general the more capable rigs are worked harder than the less capable ones and comparing their towing economy numbers is misleading.
