Help with physics of dolly turning

Since I've hit the stops for sure, what is 'giving' that allowed those turns to be made? I'd like to understand the physics to see where the stress goes.

The stress is everywhere...

• The dolly is pushing sideways on the receiver hitch in an attempt to not be turned any sharper
• The front tires are being pulled in opposite directions on the car. On a right turn, the driver's tire is being pulled forward, and the passenger tire is being pushed backward
• The dolly tires experience a side load force that would push them to the inside of the turn (a right turn would cause the dolly to want to slide to the right)
• And the car's rear tires will want to slide to the outside of the turn (slide to the left)

Since the lightest axle between the rear of the MH, the dolly, and the car's rear axle, is the car's rear axle. You can expect that on a tight turn the backend of the car will slide to the side, just as a dual axle trailer will scrub one of the axles on a tight turn.
