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 found no difference in handling a 12K equipment trailer tween my 05 dually with 8500 lbs of suspension, and my 96 K3500 that had singles, ONCE I changed out the SW setup with an 8500 lbs suspension.
I would also be willing to bet, generally speaking, that if you took a rig with singles, that are AS WIDE, same suspension tire capacity etc as the dually, BOTH would handle any given trailer the same. Most tests I have seen comparing semis with super singles and duals, the SS setup handles BETTER than the dual tired drive setups. Real issue is to a degree, the human factor.
This is not to say that some single tire tread designs may not be as good as some dual tread options.....Most SS tires I have seen advertised are more hwy oriented. If you drive in snow.....I would imagine a dual setup with traction tires would do better. With or with out chains.
But from a typical pickup standpoint. Duals will generally do better with larger loads than singles etc.
