Owned a dually since 2005, after about 300 miles getting used to it, it is just another vehicle. As others have said parking garages and some drive thrus can be a little tight. Otherwise enjoy the ride, the stability, and the ability to carry a substantial payload. In the rain the duals keep others at a distance since they put out so much spray. Probably would want to get mud flaps. I would have another without even thinking about it. At a steady 65 mph not towing mine gets about 20-21 mpg. I am not sure the SRW would get that much better mileage. Tire time is the downside of a dually, six skins to purchase.
My father has a 2005 Dodge SRW 3500 with the low HP engine. He gets 24 empty. If you need duals I would choose the Ram over the Ford because with Ram I believe you can choose duals and still get a 3:42 rear axle so I wouldn't expect the fuel economy to drop as much. My srw Ford is not great on fuel and the 3:73 gears and smaller tires of the dually would likely make it terrible.
