What is the difference?
I am new to the 350 size ford truck. I have owned only 150's and 250's. So forgive me if this question is stupid to some.
-What is the difference between a 4 tire rear ended F350 (normal dually) and a two tire rear ended F350?
Any light on this subject is appreciated.

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!!!

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.

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
