Load carrying capacity, for one. A Dually (4 tires in the rear) lends itself better to pulling heavy loads due to:
1) wider stance
2) 4 tires can support more weight than 2 (weight distribution)
3) steeper gears (daullies come with 4.10s standard, SRWs get 3.73s with 4.10s optional)
If you're not towing heavy, I.E. 10,000lbs+ then you don't really need the dually...but they are SUH-WEET lookin' rigs!!!

It also provides better stability / sway control and offers better traction and worse fuel mileage. We won't mention how it doesn't quite fit in those "Compact Car Only" parking spaces.

Don't get me started on teeny tiny parking spaces. Even us 3/4 ton people have a hard time parking sometimes. I had a truck full of girls (6 of us) a few weeks ago and had to wedge myself into this teeny tiny parking spot at an Applebees. U should have seen all of them trying to get out in their heels and whatnot with the door only open about 6 inches. hah.
Ok i'm done. Back to the subject at hand.
All I really know about duallys is that you get 32% more tires to buy & you can haul more weight with em.

if they are geared the same the fuel milage is close

But if the truck itself weighs more, wouldn't that have an impact on mileage? Heavier rear end and double meats on back...I would think that'd make a difference with MPGs.

Of course it will. Not to mention more wind resistance. I've owned 2 dually's in my life, one POS Dodge and one very nice Ford PSD, but would never own another. I had no intention of keeping the POS so I let the rear tires wear down to not enough tread anymore. On a rain slick highway, going bald duals, are like driving on ice, maybe even worse.

You're right. I didn't mean to make it sound like a huge difference if they're geared the same, but the increased rolling resistance along with the additional fenders will tend to drop MPG's about 1 to 1.5 in my experience.
Of course you can also loose MPG's by going with the 4 wheel drive option that sits up higher. (No this was not a reference to small females with big lifts and a lead foot )
