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 did find this testing that was done for the van transportation business. It's long but seems to prove the DRW will have less roll over rates.

Dual Rear Wheels (DRW) are available with either the 4x2 or 4x4 drive system. Dual
rear wheels help increase rear traction, towing stability and provide increased rear
axle weight ratings. The Front Suspension on F-250 4x2 models is an independent
Twin I-Beam design. The optional Heavy Service Suspension Package includes Heavy
service front springs, auxiliary rear springs (SRW) and steering damper. Super Duty F-
250 Pickups (and Pickup Box Delete models) feature a Ladder-type Frame with rear
kickup that is wider than the Super Duty Chassis Cab frame.
I would and will agree when using these vans or pickups as models. BUT, if you make the vans the same width with a wide(r) single wheel, same overall width, suspension etc, I would hazard a strong guess that the results will and would be very similar in the handling department. This is what has been found on semi tractors and trailers.
