The never ending debate..SRW vs DRW
So I've been reading for days about this and have read mixed reviews on the topic all of which don't directly relate to my situation so I thought'd I'd ask someone with some experience towing. I j...

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.
THe dually axle is essentially longer because it has another hub on both ends. This is where the stability comes from. Think of outriggers on a boat. Same idea.
