I'm not a Ford guy. I have a 2015 3500 Crew Dually. It rides like a Cadillac empty and tows my 375 Northpoint REALLY well.
However, I do drive an F450 for work and I will say the turning radius on it is tighter than my boss's F150 work truck. The other thing on a 450 is the rubber. My Silverado has 17", my 450 has 19.5's. 17" Michelin LTX's are bad enough in price and the 19.5 G647 up front and the G622's on the back you'll need a 2nd mortgage for.
