In my opinion, I would rather drive a dually any day, even if it means parking at the end of the parking lot. One thing I don't think anyone has mentioned is the speed you plan to tow. I get better mileage towing on rural two lane roads than interstates because I go slower. The bigger the frontal area of the trailer, the more speed seems to make a difference. We went on a 7500 mile trip out west last summer with a '07 3500 Duramax-Allison combo pulling a 12,000 lb. fiver and averaged 11 mpg while we were gone. A couple thousand of those miles were sightseeing without the trailer.
