You guys are pissing up a rope. Nothing you say will change Harley's mind. I've already pointed out that certain vehicles are designed by the manufacturer to be towed 4 down with specific instructions. He doesn't buy it. I pointed out that physically there is no difference on the towing vehicle between the effect of pulling a trailer and pulling a toad when you need to brake. He wants to see that written in a statute somewhere instead of the laws of physics.
Harley and Ducksface just need to go into a corner and argue themselves blue in the face.
