After my first dually, I will never go back to a single. I love the highway stability in adverse conditions, towing in the wind, passing by semis in the other direction etc.
I personally like the LCF that the big 3 duallys have. (Look cool factor)
Some people argue - more tires to buy! Who cares, big deal.... every 50K miles you gotta put 30% more into rubber. Divide that out over the miles and it's not that bad.
Yes, you have to learn to watch the back in tight turns around obstacles, but it becomes second nature after a short while.
I park a little further away in store lots and such. I'm not afraid to walk a few feet more.
I had a customer once, the proverbial " little old lady", look out at my truck and exclaim " Oh look, a truck with hips!"
