I sort of did the same survey as Superduty123 - I didn't actually record the SRW vs DRW numbers, but there were way more SRW towing 5th wheel RVs than DRW - at least the ratio noted by the OP. Trucks hauling big rear overhang campers (ours isn't) and heavy freight or livestock/horse type gooseneck trailers were majority DRW.
Since switching our SRW to 19.5 steel casing tires own our paid for truck have found exactly what Golden_HVAC said - lateral tire sidewall flex is way less = increased "stability". We still enjoy exceptional directional stability and traction in snow and on packed snow or ice, and still able to park in one stall.
on edit - WingedOne's pictures are a great illustration. The SRW has single range E flexiwall tires, and shorter wheelbase. It should feel less stable than the new truck. If the new truck had steel casing 19.5s and SRW, it would not feel a whole lot different than it does now...
