Saw this Harley on the back of a 5er yesterday

I explained earlier why only 40 lbs transferred off the pin with your swivel wheel trailer. That would not be the case with a pure cantilever load. With a cantilever load and the effective pivot point at the centerline between the axles, force x distance ahead of the effective pivot point MUST equal force x distance behind the effective pivot point. The laws of physics are immutable.
