Pickup truck tow vehicle stability tests
Always lots of anecdotal statements on rv.net around dual wheel vs single rear wheel "stability". Anyone have any links that point to actual testing results under controlled conditions?

I too brought it up. 4 tires at 50% load will have a lot less sidewall flex than 2 at 100% load... Given one RAW.
A DRW is over-tired for the load, which is never a bad thing. When I went from traveling with my rear tires at 95-100% loaded to 80% loaded my tire flex and stability went way up, despite adding about 15% more load and a higher CG.
Having made various tire and suspension mods over the years tire flex feels much different than suspension flex, even thou it is often in smaller increments.
