2014 Ram 3500 without Aisin Tranny
I can get an incredible deal on a new Ram 3500 SRW, 6.7 Cummins, but it does not have the Aisin tranny. My eventual intentions would be to tow a 16,000 lb. fiver. Would it be worth me ordering a 201...

SRW vs DRW is always a debate. Yes there is more stability when comparing apples to apples. 4 LRE tires are more stable than 2, and it's not just the width (really little with the width IMHO) it's the stifness. If the outers where the same width as the SRW and you could keep the springs in the same spot the DRW would still be more stable.
Both the SRW and DRW pivot the suspension at the same point, so any sway reduction or stability improvement on a DRW is from a lack of tire deflection.
Super single, for a pickup they are the 19.5" conversions. While it's probably not quite as stable as a DRW I am willing to bet that for most loads it is. LRG sidewalls are much stiffer than LRE, and designed differently.. but somehow they really don't ride any worse on a 1 ton.
So 2 tires at 110psi to carry 9,000lbs or 4 tires at 65 psi to carry 9,350 lbs (limits on SRW (245/70R19.5) and DRW applications for same truck, i.e. 03-12 Dodge). Probably about the same.
Stock for stock a DRW will walk all over a SRW, but if a DRW isn't an option it's not difficult to make a SRW compete in all aspects with a DRW.. and it still is easy to drive on tight back roads.
All other things being equal this is probably accurate. However, in late model trucks, at least Ford, you also get different components such as better brakes and a stronger rear axle.
