If everything is working right, there is no way for towing a small car, even on a dolly, to make a great difference. My guess is that unless you have issues with your dolly and/or toad, that the problem is your ACE is not as fuel efficient as you hope.
There is nothing inherently bad about the V10 when towing.
If you had a V10 in a pickup, and then towed a 5th wheel, obviously the MPGs will drop like crazy, but that's because the load on engine is much greater, not because it suddenly became inefficient.
Similarly, if you have a huge Class A it's going to get low MPGs because the load on engine is high. Adding a small car behind the Class A can't make that big a difference -- assuming things are set up and working correctly.
I think +/- 1/2 MPG reduction when towing a mid-size car is a good approximation. If it's a lot more than that I'd start looking for problems.
