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?

Maybe some us had really well performing SRW's that the delta between them and DRW is not that much. My F250 with modified suspension and 19.5" wheels did extremely well with the weight it hauled plus towing weight behind it. Now that I have DRW, the biggest change I feel is how the heavier stock spring pack handles the same weight verses my modified suspension.
SO SPEND SOME MONEY ON YOUR DUALLY AND MODIFY IT!!
Oh thats right, there is no need.:B
You missed the point completely. His point was the suspension system on the DRW is the primary reason why they "feel" more stable. Unless you're actually to the point of almost rolling your rig, the width isn't so important. A wider stance just means less force is needed at the tire(s) to prevent tilting. A strong single tire at a narrow stance can certainly resist tilting as well as a weaker one(s) at a wide stance but most would not like riding on that firm of a tire.
