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?

Well, maybe what the OP is trying to quantify is "How" much better is a DRW versus SRW. Anecdotal evidence is one thing, but what would be great is to take out 2 vehicles and run them in the same closed courses with the same trailer that is in both their ranges (probably near the top of the SRW vehicle).
This reminds me of a write-up I saw somewhere of 5'er versus TT for towing. Feeling wise, the 5'er setup felt planted and there was less sway, the TT felt like it required more work to ensure it was driving straight. However, in emergency maneuvers, the 5'er was tipping quite heavily at lower speeds versus the higher speeds in which the tester was able to perform an emergency sway/lane change maneuver with the TT. However, the tester did note that the 5'er felt more planted even though it lifted tires on one side. I only wish where I read this at, but it was interesting. The same tests could be conducted between a SRW versus DRW to finally draw out how much more stability one could gain by getting a DRW. Sure, intuitively you have a wider footprint, but how much more stability does that really buy you? Everybody's subjective opinion does not necessarily line up with one another, however, hard numbers tell another story.
