Two sidewalls per tire give you eight sidewalls.
I will argue the wider track does not do as much for stability because the frame is not hard mounted to the axle. The width of the suspension is the same on a SRW and DRW. It will help tracking if the rear width of the truck matches the trailer.
The DRW's stability advantage is due to stiffer sidewalls by having twice the number of tires and typically heavier suspension components. If you put stiffer sidewall tires and suspension on a SRW, you will see stability also increased.
^This.
In laymans terms, a dually is a ready equipped machine. A srw truck takes a bit of work to get more stability and load carrying capacity.
The important point a lot of the weight cops on here seem to ignore is, in general, 2500 through 3500 drw trucks are the same chassis, with more or less spring capacity and more or less tires.
Vehicle body roll is centered around the spring mounting locations. Those are the pivot points and that does not change with a dually.

Regardless of the attachment method the added width will increase stability. Imagine a bike with training wheels. Move those training wheels inward they have less effect. Spread them wider and the bike becomes harder to tip over.
While the frame is not hard mounted to the axle, the axle does not flex. The suspension will eventually hit a stop.
On a dually the suspension/axle is wider than the frame producing stability.

It would seem that we were talking at cross purposes, and I've misunderstood you. I thought you were saying the only time a dually is better is if you need the payload that a dually offers over a SRW.
