As far as "stability" of a dually, I've never been sure what that means. Most lean is in the springs/suspension not the number of tire. No doubt more tires increase number 5 above (GVWR) but they have little effect on sway and leaning or "stability."
All else being equal, shorter wider tires are more stable. DRW obviously has more width.
The suspensions are not the same. The spring packs are different on a DRW. The rear differentials are also different. Furthermore, they have different brakes. Both because the intended use is to haul more weight.
I started with a SRW, and changed to a DRW when I no longer needed a SRW as my daily driver to fit in parking spaces. With my SRW, I avoided carrying anything extra down to reducing the amount of water I carried. I have no issues any more with what I carry. I even towed a TT behind on a trip a few years ago over 500 miles each way.
By all means, buy a SRW if you want or need one, but let's not pretend they are equivalent or close to the same. They are literally made for different purposes. As noted, brakes are different, so stopping is incredibly different as well.
